Cautionary Note Regarding Forward-Looking Information

This Quarterly Report on Form 10-Q ("Form 10-Q") contains forward-looking statements, within the meaning of the Private Securities Litigation Reform Act of 1995, which are subject to risks and uncertainties. All statements other than statements of historical fact are forward-looking statements. Many of the forward-looking statements are located in Part I, Item 2 of this Form 10-Q under the heading "Management's Discussion and Analysis of Financial Condition and Results of Operations." Forward-looking statements discuss our current expectations and projections relating to our financial position, results of operations, plans, objectives, future performance and business. You can identify forward-looking statements by the fact that they do not relate strictly to historical or current facts. These statements may include words such as "aim," "anticipate," "believe," "estimate," "expect," "forecast," "outlook," "potential," "project," "projection," "plan," "intend," "seek," "may," "could," "would," "will," "should," "can," "can have," "likely," the negatives thereof and other similar expressions. All forward-looking statements are subject to known and unknown risks, uncertainties and other important factors that may cause actual results to be materially different.

While we believe that our assumptions are reasonable, it is very difficult to predict the impact of known factors, and it is impossible to anticipate all factors that could affect our actual results. All forward-looking statements are expressly qualified in their entirety by these cautionary statements. You should evaluate all forward-looking statements made in this Form 10-Q in the context of the risks and uncertainties disclosed in Part I, Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2014 filed with the U.S. Securities and Exchange Commission (the "SEC") under the heading "Risk Factors."

The forward-looking statements included in this Form 10-Q are made only as of the date hereof. We undertake no obligation to publicly update or revise any forward-looking statement as a result of new information, future events or otherwise, except as otherwise required by law.

The computation does not consider the 5,750,000 shares of Class A common stock issued to investors in our initial public offering or the 339,306 shares of Class A common stock issued upon settlement of outstanding unit appreciation rights.

NOTE 1: ORGANIZATION AND 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, crinkle-cut fries, shakes, frozen custard, beer, wine and more. As of September 30, 2015, there were 75 Shacks in operation, system-wide, of which 41 were domestic company-operated Shacks, five were domestic licensed Shacks and 29 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 ("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' membership interests ("Original SSE Equity Owners") for LLC Interests and (iii) appoint Shake Shack as the sole managing member of SSE Holdings. See Note 8.

▪ 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 Original SSE Equity Owners on a one-to-one basis with the number of LLC Interests they own. See Note 8.

▪ We acquired, by merger, two entities that were owned by former indirect members of SSE Holdings ("Former SSE Equity Owners"), 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 SSE Holdings members subsequent to the Merger (the "Continuing SSE Equity Owners") 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 have a minority economic interest in SSE Holdings, we have 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 condensed 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 affiliates of the Former SSE Equity Owners and certain of the Continuing SSE Equity Owners (the "Selling Stockholders"). We did not receive any proceeds from the sale of shares of Class A common stock offered by the Selling Stockholders. The shares sold in the offering consisted of (i) 844,727 existing shares of Class A common stock held by the Former SSE Equity Owners and (ii) 3,155,273 newly-issued

8

shares of Class A common stock issued in connection with the redemption of 3,155,273 LLC Interests by the Continuing SSE Equity Owners that participated in the offering. Simultaneously, and in connection with the redemption, 3,155,273 shares of Class B common stock were surrendered by the Continuing SSE Equity Owners and canceled. Additionally, in connection with the redemption, we received 3,155,273 newly-issued LLC Interests, increasing our total ownership interest in SSE Holdings. Following the completion of the secondary offering, we own 42.0% of SSE Holdings and the Continuing SSE Equity Owners own the remaining 58.0% of SSE Holdings.

NOTE 2: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements include the accounts of Shake Shack Inc. and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. These interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and on a basis consistent in all material respects with the accounting policies described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014 ("2014 Form 10-K"). In our opinion, all adjustments, which are normal and recurring in nature, necessary for a fair presentation of our financial position and results of operation have been included. Certain reclassifications have been made to prior period amounts to conform to the current year presentation. Operating results for interim periods are not necessarily indicative of the results that may be expected for a full fiscal year.

The accompanying Condensed Consolidated Balance Sheet as of December 31, 2014 has been derived from the audited financial statements at that date but does not include all of the disclosures required by GAAP. These interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes thereto included in our 2014 Form 10-K.

We do not have any components of other comprehensive income recorded within our condensed consolidated financial statements, and, therefore, do not separately present a statement of comprehensive income in our condensed consolidated financial statements.

Fiscal Year

We operate on a 52/53 week fiscal year ending on the last Wednesday in December. Fiscal 2015 contains 52 weeks and ends on December 30, 2015. Fiscal 2014 contained 53 weeks and ended on December 31, 2014. Unless otherwise stated, references to years in this report relate to fiscal years.

Use of Estimates

The preparation of these condensed consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of sales and expenses during the reporting period. Actual results could differ from those estimates.

Recently Issued Accounting Pronouncements       

In August 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2015-15, Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements ("ASU 2015-15"), which clarifies the guidance set forth in Accounting Standards Update No. 2015-03, Simplifying the Presentation of Debt Issuance Costs ("ASU 2015-03"), issued in April 2015. ASU 2015-03 requires that debt issuance costs related to a recognized liability be presented on the balance sheet as a direct reduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected. ASU 2015-15 provides additional guidance regarding debt issuance costs associated with line-of-credit arrangements, stating that the SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred issuance costs ratably over the term of the line-of-credit arrangement. ASU 2015-03 is effective for reporting periods beginning after December 15, 2015. The adoption of ASU 2015-03 and ASU 2015-15 is not expected to have a material effect our consolidated financial position, results of operations or cash flows.

In July 2015, the FASB issued Accounting Standards Update No. 2015-11, Simplifying the Measurement of Inventory ("ASU 2015-11"). Under ASU 2015-11 entities should measure inventory that is not measured using last-in, first-out (LIFO) or the retail inventory method, including inventory that is measured using first-in, first-out (FIFO) or average cost, at the lower of cost or net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. ASU 2015-11 is effective for reporting periods beginning after December 15, 2016 and is to be applied prospectively. The adoption of ASU 2015-11 is not expected to have a material effect on our consolidated financial position, results of operations or cash flows.

In April 2015, the FASB issued Accounting Standards Update No. 2015-05, Customers' Accounting for Fees Paid in a Cloud Computing Arrangement ("ASU 2015-05"). ASU 2015-05 provides guidance in evaluating whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the software license element of the arrangement should be accounted for as an acquisition of a software license. If the arrangement does not contain a software license, it should be accounted for as a service contract. ASU 2015-05 is effective for reporting periods beginning after December 15, 2015 and may be adopted either retrospectively or prospectively. We are currently evaluating the impact ASU 2015-05 will have on our consolidated financial statements.

In February 2015, the FASB issued Accounting Standards Update No. 2015-02, Consolidation ("ASU 2015-02"). ASU 2015-02 amends the existing guidance to: (i) modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities (VIEs) or voting interest entities; (ii) eliminate the presumption that a general partner should consolidate a limited partnership; (iii) affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships and (iv) provide a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. ASU 2015-02 is effective for reporting periods beginning after December 15, 2015. We are currently evaluating the impact ASU 2015-02 will have on our consolidated financial statements.

In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"). ASU 2014-09 supersedes the existing revenue recognition guidance and clarifies the principles for recognizing revenue. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. In August 2015, the FASB issued an update to ASU 2014-09 deferring the effective date for public entities, on a retrospective basis, to annual reporting periods beginning after December 15, 2017. Early adoption is permitted, subject to certain conditions. We are currently evaluating the impact ASU 2014-09 will have on our consolidated financial position, results of operations and cash flows.

NOTE 3: FAIR VALUE MEASUREMENTS

The carrying value of our financial instruments, including cash, accounts receivable, accounts payable, and accrued expenses as of September 30, 2015 and December 31, 2014 approximated their fair value due to the short-term nature of these financial instruments. Assets and liabilities that are measured at fair value on a non-recurring basis include our long-lived assets. There were no impairments recognized during the thirteen and thirty-nine weeks ended September 30, 2015 and September 24, 2014.

NOTE 7: DEBT

In January 2015, we executed a Third Amended and Restated Credit Agreement, which became effective on February 4, 2015 (together with the prior agreements and amendments, the "Revolving Credit Facility"), which provides for a revolving total commitment amount of $50,000, of which $20,000 is available immediately. The Revolving Credit Facility will mature and all amounts outstanding will be due and payable five years from the effective date. The Revolving Credit Facility permits the issuance of letters of credit upon our request of up to $10,000. Borrowings under the Revolving Credit Facility bear interest at either: (i) LIBOR plus a percentage ranging from 2.5% to 3.5% or (ii) the prime rate plus a percentage ranging from 0.0% to 1.0%, depending on the type of borrowing made under the Revolving Credit Facility. As of December 31, 2014, amounts outstanding under the Revolving Credit Facility totaled $32,000, and were classified as short-term borrowings on the Condensed Consolidated Balance Sheets. During the thirty-nine weeks ended September 30, 2015, we borrowed an additional $4,000 in principal under the Revolving Credit Facility. In February 2015, we repaid the entire outstanding balance of $36,000 using a portion of the proceeds we received from our IPO and, as of September 30, 2015, there were no amounts outstanding under the Revolving Credit Facility. We had $19,920 of availability as of September 30, 2015, after giving effect to $80 in outstanding letters of credit.

The Revolving Credit Facility is secured by a first-priority security interest in substantially all of the assets of SSE Holdings and the guarantors. The obligations under the Revolving Credit Facility are guaranteed by each of SSE Holdings' wholly-owned domestic subsidiaries (with certain exceptions).

The Revolving Credit Facility contains a number of covenants that, among other things, limit our ability to, subject to specified exceptions, incur additional debt; incur additional liens and contingent liabilities; sell or dispose of assets; merge with or acquire other companies; liquidate or dissolve ourselves; pay dividends or make distributions; engage in businesses that are not in a related line of business; make loans, advances or guarantees; engage in transactions with affiliates; and make investments. In addition, the Revolving Credit Facility contains certain cross-default provisions. We are required to maintain a specified consolidated fixed-charge coverage ratio and a specified funded net debt to adjusted EBITDA ratio, both as defined under the Revolving Credit Facility. As of September 30, 2015, we were in compliance with all covenants.

In March 2013, we entered into a promissory note in the amount of $313 in connection with the purchase of a liquor license. Interest on the outstanding principal balance of this note is due and payable on a monthly basis from the effective date at a rate of 5.0% per year. The entire principal balance and interest is due and payable on the earlier of the maturity date, which is the expiration of the lease in June 2023, or the date of the sale of the license. As of September 30, 2015 and December 31, 2014, the outstanding balance of the promissory note was $313.

NOTE 8: STOCKHOLDERS' EQUITY

Amendment and Restatement of Certificate of Incorporation

On February 4, 2015, we amended and restated our certificate of incorporation to, among other things, provide for the (i) authorization of 200,000,000 shares of Class A common stock with a par value of $0.001 per share; (ii) authorization of 35,000,000 shares of Class B common stock with a par value of $0.001 per share; (iii) authorization of 10,000,000 shares of undesignated preferred stock that may be issued from time to time by our Board of Directors in one or more series; and (iv) establishment of a classified board of directors, divided into three classes, each of whose members will serve for staggered three-year terms.

Holders of our Class A and Class B common stock are entitled to one vote per share and, except as otherwise required, will vote together as a single class on all matters on which stockholders generally are entitled to vote. Holders of our Class B common stock are not entitled to receive dividends and will not be entitled to receive any distributions upon the liquidation, dissolution or winding up of the Company. Shares of Class B common stock may only be issued to the extent necessary to maintain the one-to-one ratio between the number of LLC Interests held by the Continuing SSE Equity Owners and the number of shares of Class B common stock held by the Continuing SSE Equity Owners. Shares of Class B common stock are transferable only together with an equal number of LLC Interests. Shares of Class B common stock will be canceled on a one-for-one basis upon the redemption or exchange any of the outstanding LLC Interests.

We must, at all times, maintain a one-to-one ratio between the number of outstanding shares of Class A common stock and the number of LLC Interests owned by us (subject to certain exceptions for treasury shares and shares underlying certain convertible or exchangeable securities).

Initial Public Offering

As described in Note 1, 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 LLC Interests from SSE Holdings at a price per interest equal to the initial public offering price of our Class A common stock.

In connection with our IPO, we issued 30,160,694 shares of Class B common stock to the Original SSE Equity Owners.

Secondary Offering

As described in Note 1, 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 the Selling Stockholders. We did not receive any proceeds from the sale of shares of Class A common stock offered by the Selling Stockholders. The shares sold in the offering consisted of (i) 844,727 existing of existing Class A common stock and (ii) 3,155,273 newly-issued shares of Class A common stock issued in connection with the redemption 3,155,273 LLC Interests. Simultaneously, and in connection with the secondary offering, 3,155,273 shares of Class B common stock were surrendered and canceled. Following the completion of the secondary offering, 15,213,420 shares of Class A common stock and 21,036,580 shares of Class B common stock were outstanding.

SSE Holdings Recapitalization

As described in Note 1, on February 4, 2015, we amended the SSE Holdings LLC Agreement to, among other things, (i) provide for a new single class of common membership interests in SSE Holdings, the LLC Interests, and (ii) exchange all of the then-existing membership interests of the Original SSE Equity Owners for LLC Interests.

The LLC Agreement also provides that holders of LLC Interests may, from time to time, require SSE Holdings to redeem all or a portion of their LLC Interests for newly-issued shares of Class A common stock on a one-for-one basis. Upon receipt of a redemption request, we may, instead, elect to effect a direct exchange of LLC Interests directly with the holder. Additionally, we may elect to settle any such redemption or exchange in shares of Class A common stock or in cash. In the event of cash settlement, we would issue new shares of Class A common stock and use the proceeds from the sale of these newly-issued shares of Class A common stock to fund the cash settlement, which, in effect, limits the amount of the cash payment to the redeeming member. In connection with any redemption or exchange, we will receive a corresponding number of LLC Interests, increasing our total ownership interest in SSE Holdings. Additionally, an equivalent number of shares of Class B common stock will be surrendered and canceled.

The amendment also requires that SSE Holdings, at all times, maintain (i) a one-to-one ratio between the number of outstanding shares of Class A common stock and the number of LLC Interests owned by us and (ii) a one-to-one ratio between the number of shares of Class B common stock owned by the Continuing SSE Equity Owners and the number of LLC Interests owned by the Continuing SSE Equity Owners.

Member Distributions

On December 15, 2014, the Board of Directors of SSE Holdings approved a special distribution to its members, to the extent the gross proceeds from the IPO exceeded the anticipated gross proceeds (including as a result of the exercise by the underwriters of their option to purchase additional shares of Class A common stock), in an amount equal to the product of (i) the increased gross proceeds and (ii) 0.273, to be paid from the proceeds of the IPO (the "Additional Distribution"). On February 4, 2015, SSE Holdings paid the Additional Distribution to certain of the Original SSE Equity Owners in the amount of $11,125.

NOTE 9: NON-CONTROLLING INTERESTS

On February 4, 2015, we used the net proceeds from our IPO to purchase 5,750,000 newly-issued LLC Interests. Additionally, in connection with the Organizational Transactions, we acquired 5,968,841 LLC Interests. Pursuant to the LLC Agreement, we received 339,306 LLC Interests as a result of the issuance of 339,306 shares of Class A common stock in settlement of the outstanding UARs.

In August 2015, in connection with the secondary offering, 3,155,273 LLC Interests were redeemed by the Selling Stockholders for newly-issued shares of Class A common stock and we received 3,155,273 newly-issued LLC Interests, increasing our total ownership interest in SSE Holdings.

Equity-based compensation expense	$	1,172	$	41	$	15,509	$	124

Amounts are included in general and administrative expense on the Condensed Consolidated Statements of Income (Loss). No income tax benefits were recognized related to equity-based compensation during the thirteen and thirty-nine weeks ended September 30, 2015 and September 24, 2014.

Unit Appreciation Rights

Prior to the IPO, we maintained a Unit Appreciation Rights Plan (the "UAR Plan"), effective in fiscal year 2012, and as amended, whereby we had the authority to grant up to 31,303 unit appreciation rights ("UARs") to employees. The UARs granted were subject to continued employment and were only exercisable upon a qualifying transaction, which was either a change of control or an initial public offering, each as defined in the UAR Plan. Upon the occurrence of a qualifying transaction, each UAR entitled the holder to receive a payment from us. Such payment and related compensation expense was determined by multiplying (i) the excess, if any, of the qualifying transaction price over the base amount of the UAR, by (ii) the stated number of Class B units deemed covered by the UAR. Effective October 30, 2014, the UAR Plan was amended to provide that the payment to which UAR holders were entitled upon the occurrence of a qualifying transaction would be in the form of securities of the Company or one of its affiliates or such other form of payment as we determined in our sole discretion. The UARs would have terminated on the tenth anniversary of the grant date or upon termination of employment, if earlier.

A summary of UAR activity for the thirty-nine weeks ended September 30, 2015 is as follows:

		UARs		Weighted Average Base Price
Outstanding at beginning of period		22,554		$	193.51
	Granted	—		—
	Forfeited	—		—
	Vested and settled	(22,554	)	(193.51		)
Outstanding at end of period		—		$	—

No compensation expense was recorded during the thirteen and thirty-nine weeks ended September 24, 2014 related to the outstanding UARs as we determined that, as of the period end, it was not probable that a qualifying transaction would occur.

As described in Note 1, on February 4, 2015, we amended and restated the SSE Holdings LLC Agreement to, among other things, (i) provide for a new single class of common membership interests, the LLC Interests, and (ii) exchange all of the then-existing membership interests of the Original SSE Equity Owners for LLC Interests (together, the "Recapitalization Transaction"). The 22,554 outstanding UARs that were settled in connection with the IPO equate to 767,947 LLC Interests with a weighted average base price of $5.68, after giving effect to the Recapitalization Transaction.

Our IPO constituted a qualifying transaction under the terms of the UAR Plan, resulting in a qualifying transaction price of $715.02. 339,306 shares of Class A common stock were issued upon the settlement of the 22,554 outstanding UARs, net of employee withholding taxes. We recognized compensation expense of $11,762 during the thirty-nine weeks ended September 30, 2015 upon settlement of the outstanding UARs.

Restricted Class B Units

Prior to the IPO, we granted restricted Class B units to certain of our executive officers. These awards were to vest in equal installments over periods ranging from three to five years. If not already fully vested, these units would fully vest (i) upon the occurrence of a change in control event or (ii) upon the occurrence of an initial public offering, each as defined in the grant agreement, and any unrecognized compensation expense related to these non-vested units would be subject to acceleration.

A summary of restricted Class B unit activity for thirty-nine weeks ended September 30, 2015 is as follows:

		Units		Weighted Average Grant Date Fair Value
Outstanding at beginning of period		7,227		$	92.31
	Granted	—		—
	Vested	(7,227	)	(92.31		)
	Forfeited	—		—
Outstanding at end of period		—		$	—

The IPO constituted a transaction under the terms of the restricted Class B unit awards that resulted in the accelerated vesting of all then-outstanding awards, and recognition of the unrecognized compensation expense related to those awards. During the thirty-nine weeks ended September 30, 2015, we recognized $605 of equity-based compensation expense upon the vesting of these awards. The total fair value of restricted Class B units that vested during the thirty-nine weeks ended September 30, 2015 was $667. After giving effect to the Recapitalization Transaction, the 7,227 restricted Class B units that vested in connection with our IPO equate to 158,251 LLC Interests with a weighted-average grant date fair value of $4.22.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(in thousands, except unit, share, per unit and per share amounts)

(Unaudited)

In January 2015, we adopted the 2015 Incentive Award Plan (the "2015 Plan") under which we may grant up to 5,865,522 stock options and other equity-based awards to employees, directors and officers. In connection with the IPO, we granted 2,622,281 stock options to our directors and certain employees. The stock options were granted with an exercise price of $21.00 per share and vest equally over periods ranging from one to five years.

The fair value of stock option awards was determined on the grant date using the Black-Scholes valuation model based on the following weighted-average assumptions:

	Thirty-Nine Weeks Ended September 30, 2015
Expected term (years)(1)	7.5
Expected volatility(2)	35.1	%
Risk-free interest rate(3)	1.6	%
Dividend yield(4)	—	%

(1) Expected term represents the estimated period of time until an award is exercised and was determined using the simplified method.

(2) Expected volatility is based on the historical volatility of a selected peer group over a period equivalent to the expected term.

(3) The risk-free rate rate is an interpolation of yields on U.S. Treasury securities with maturities equivalent to the expected term.

(4) We have assumed a dividend yield of zero as we have no plans to declare dividends in the foreseeable future.

A summary of stock option activity for thirty-nine weeks ended September 30, 2015 is as follows:

		Stock Options		Weighted Average Exercise Price
Outstanding at beginning of period		—		$	—
	Granted	2,622,281		21.00
	Exercised	—		—
	Forfeited	(41,425	)	(21.00		)
Outstanding at end of period		2,580,856		$	21.00

The weighted-average grant date fair value of stock options granted during the thirty-nine weeks ended September 30, 2015 was $8.53. As of September 30, 2015, there were 2,580,856 stock options outstanding, of which none were exercisable. As of September 30, 2015, total unrecognized compensation expense related to unvested stock options, including an estimate for pre-vesting forfeitures, was $19,109, which is expected to be recognized over a weighted-average period of 4.3 years.

NOTE 11: INCOME TAXES

As a result of the IPO and Organizational Transactions, we became the sole managing member of SSE Holdings, which is treated as a partnership for U.S. federal and most applicable state and local income tax purposes. As a partnership, SSE Holdings is not subject to U.S. federal and certain state and local income taxes. Any taxable income or loss generated by SSE Holdings is passed through to and included in the taxable income or loss of its members, including us, on a pro rata basis. We are subject to U.S. federal income taxes, in addition to state and local income taxes with respect to our allocable share of any taxable income or loss of SSE Holdings. We are also subject to withholding taxes in foreign jurisdictions.

A reconciliation of income tax expense computed at the U.S. federal statutory income tax rate to the income tax expense recognized is as follows:

Pro Forma Financial Information

For periods prior to the IPO and Organizational Transactions, our income taxes represent those of SSE Holdings, our predecessor, and relate solely to foreign withholding taxes and certain LLC entity-level taxes. As a result of the IPO and Organizational Transactions that occurred on February 4, 2015, we are subject to U.S. federal and certain state and local income taxes with respect to our allocable share of any taxable income or loss generated by SSE Holdings. The pro forma financial information presented on the Condensed Consolidated Statements of Income (Loss) for the thirty-nine weeks ended September 30, 2015 has been computed to reflect a benefit from income taxes at an effective tax rate of 61.6%. The amounts were calculated assuming the Organizational Transactions occurred on January 1, 2015 and were based on the statutory rates in effect during the period.

Tax Receivable Agreement

We expect to obtain an increase in our share of the tax basis of our share of the net assets of SSE Holdings when LLC Interests are redeemed or exchanged by the Continuing SSE Equity Owners and other qualifying transactions. This increase in tax basis may have the effect of reducing the amounts that we would otherwise pay in the future to various tax authorities. The increase in tax basis may also decrease gains (or increase losses) on future dispositions of certain capital assets to the extent tax basis is allocated to those capital assets.

On February 4, 2015, we entered into a tax receivable agreement with the Continuing SSE Equity Owners (the "Tax Receivable Agreement") that provides for the payment by us to the Continuing SSE Equity Owners of 85% of the amount of tax benefits, if any, that Shake Shack actually realizes or in some cases are deemed to realize as a result of (i) increases in the tax basis of the net assets of SSE Holdings resulting from any redemptions or exchanges of LLC Interests or any prior sales of interests in SSE Holdings and (ii) certain other tax benefits related to our making payments under the Tax Receivable Agreement.

During the thirty-nine weeks ended September 30, 2015, SSE Holdings paid a distribution in the amount of $11,125 to certain of the Original SSE Equity Owners. This distribution triggered an increase in the tax basis of the net assets of SSE Holdings subject to the provisions of the Tax Receivable Agreement. We recognized a deferred tax asset in the amount of $6,006 and a corresponding liability of $5,105, representing 85% of the tax benefits due to the Continuing SSE Equity Owners.

In August 2015, in connection with the secondary offering, 3,155,273 LLC Interests were redeemed by the Selling Stockholders for newly-issued shares of Class A common stock, resulting in an increase in the tax basis of the net assets of SSE Holdings subject to the provisions of the Tax Receivable Agreement. We recognized a deferred tax asset in the amount of $102,719 and a corresponding liability of $87,311. As of September 30, 2015, the total amount due to the Continuing SSE Equity Owners under the Tax Receivable Agreement was $92,416.

NOTE 12: EARNINGS PER SHARE

Basic earnings per share of Class A common stock is computed by dividing net income available to Shake Shack Inc. by the weighted-average number of shares of Class A common stock outstanding during the period. Diluted earnings per share of Class A common stock is computed by dividing net income available to Shake Shack Inc. by the weighted-average number of shares of Class A common stock outstanding adjusted to give effect to potentially dilutive securities.

As described in Note 1, on February 4, 2015, the SSE Holdings LLC Agreement was amended and restated to, among other things, (i) provide for a new single class of common membership interests, the LLC Interests, and (ii) exchange all of the then-existing membership interests of the Original SSE Equity Owners for LLC Interests. For purposes of calculating earnings per share, the prior period amounts have been retroactively adjusted to give effect to the above-mentioned amendment and resulting recapitalization. The computation does not consider the 5,750,000 shares of Class A common stock issued to investors in our IPO or the 339,306 shares of Class A common stock issued upon settlement of outstanding UARs in connection with the IPO.

The following table sets forth reconciliations of the numerators and denominators used to compute basic and diluted earnings per share of Class A common stock for the thirteen and thirty-nine weeks ended September 30, 2015 and September 24, 2014.

			Thirteen Weeks Ended				Thirty-Nine Weeks Ended

Earnings per share of Class A common stock—diluted			$	0.10	$	0.02	$	(0.80	)	$	0.12

2,580,856 stock options were excluded from the computation of diluted earnings per share of Class A common stock for the thirty-nine weeks ended September 30, 2015 because the effect would have been anti-dilutive as we recorded a net loss for the period.

Shares of our Class B common stock do not share in the earnings or losses of Shake Shack and are therefore not participating securities. As such, separate presentation of basic and diluted earnings per share of Class B common stock under the two-class method has not been presented. Shares of our Class B common stock are, however, considered potentially dilutive shares of Class A common stock. After evaluating the potential dilutive effect under the if-converted and two-class methods, the 21,036,580 shares of Class B common stock outstanding as of September 30, 2015 were determined to be anti-dilutive and have therefore been excluded from the computations of diluted earnings per share of Class A common stock.

As security under the terms of several of our leases, we are obligated under letters of credit totaling $160 as of September 30, 2015. The letters of credit expire on April 23, 2016 and February 28, 2026. In addition, in December 2013, we entered into an irrevocable standby letter of credit in conjunction with our home office lease in the amount of $80. The letter of credit expires in September 2016 and renews automatically for one-year periods through September 30, 2019.

Purchase Commitments

Purchase obligations include legally binding contracts, including commitments for the purchase, construction or remodeling of real estate and facilities, firm minimum commitments for inventory purchases, equipment purchases, marketing-related contracts, software acquisition/license commitments and service contracts. These obligations are generally short-term in nature and are recorded as liabilities when the related goods are received or services rendered. We also enter into long-term, exclusive contracts with certain vendors to supply us with food, beverages and paper goods, obligating us to purchase specified quantities. These volume commitments are not subject to any time limit and there are no material financial penalties associated with these agreements in the event of early termination.

Legal Contingencies

We are subject to various legal and regulatory proceedings, claims and liabilities, such as employment-related claims and slip and fall cases, which arise in the ordinary course of business and are generally covered by insurance. As of September 30, 2015, the amount of ultimate liability with respect to these matters was not material.

OVERVIEW

Shake Shack is a modern day "roadside" burger stand serving a classic American menu of premium burgers, hot dogs, crinkle-cut fries, shakes, frozen custard, beer and wine. As of September 30, 2015, there were 75 Shacks in operation, system-wide, of which 41 were domestic company-operated Shacks, five were domestic licensed Shacks and 29 were international licensed Shacks.

Development Highlights

During the quarter, we opened four domestic company-operated Shacks, consisting of (i) an additional Shack in the Central Florida market, inside Orlando's I-Drive 360, (ii) our second Austin Shack in The Domain retail development, (iii) on Long Island in the Lake Success Shopping Center in New Hyde Park and (iv) a third Shack in the Chicago market in Westfield Old Orchard in Skokle, IL.

Financial Highlights for the Third Quarter 2015

▪ Total revenue increased 67.4% to $53.3 million.

▪ Shack sales increased 70.0% to $51.3 million.

▪ Same-Shack sales increased 17.1%.

▪ Net income was $1.5 million, or $0.10 per diluted share.

▪ Shack-level operating profit*, a non-GAAP measure, increased 105.7% to $15.6 million, or 30.4% of Shack sales.

▪ Adjusted EBITDA*, a non-GAAP measure, increased 128.3% to $13.0 million.

▪ Adjusted pro forma net income*, a non-GAAP measure, increased 252.3% to $4.4 million, or $0.12 per fully exchanged and diluted share.

* Shack-level operating profit, adjusted EBITDA and adjusted pro forma net income are non-GAAP measures. Reconciliations of Shack-level operating profit to operating income, adjusted EBITDA to net income, and adjusted pro forma net income to net income, the most directly comparable financial measures presented in accordance with GAAP, are set forth on pages 25 through 27.

The third quarter of 2015 reflected the continuation of many of the positive trends we experienced in the prior quarter, including: (i) menu price increases implemented in September 2014 and January 2015 to offset higher commodity costs, (ii) the continued lift in sales due to the reintroduction of crinkle-cut fries, (iii) positive shifts in sales mix from our limited-time offering of the Roadside Shack burger and Shake of the Week program and (iv) increased brand awareness resulting from our IPO. Shack-level operating profit margins increased to 30.4% driven by these positive factors and improved leverage on fixed costs from the higher Shack sales.

Net income was $1.5 million, or $0.10 per diluted share, for the third quarter of 2015, compared to net income of $0.5 million, or $0.02 per diluted share, for the same period last year. On an adjusted pro forma basis, which excludes certain non-recurring items and assumes that all outstanding LLC Interests were exchanged for shares of Class A common stock as of the beginning of the period, we would have recognized net income of $4.4 million, or $0.12 per fully exchanged and diluted share, for the third quarter of 2015 compared to $1.2 million, or $0.03 per fully exchanged and diluted share for the the third quarter of 2014, an increase of 252.3%.

We remain committed to executing our key growth strategies of opening new domestic company-operated Shacks, capitalizing on our outsized brand awareness, growing same-Shack sales and opportunistically increasing our licensed Shacks abroad. Subsequent to the end of the quarter, we opened one international licensed Shack, as well as two additional domestic company-operated Shacks, achieving our stated goal of 12 domestic company-operated Shack openings for fiscal 2015. As a result of favorable construction and supply chain efforts, we expect to open our first Shack in Tokyo, Japan in November 2015, ahead of schedule. In addition to Japan, we are on track to open two additional international licensed Shacks during the rest of fiscal 2015. We are also well on our way towards building a strong pipeline for 2016 and beyond.

(1) As a percentage of Shack sales.

Shack Sales

Shack sales represent the aggregate sales of food and beverages in domestic company-operated Shacks. Shack sales in any period are directly influenced by the number of operating weeks in such period, the number of open Shacks and same-Shack sales. Same-Shack sales means, for any reporting period, sales for the comparable Shack base, which we define as the number of domestic company-operated Shacks open for 24 months or longer. For fiscal 2015, same-Shack sales growth is calculated on a calendar basis as we believe it more accurately reflects the performance of our business as it eliminates the impact of the extra operating week in fiscal 2014 and compares consistent calendar weeks.

Shack sales were $51.3 million for the thirteen weeks ended September 30, 2015 compared to $30.2 million for the thirteen weeks ended September 24, 2014, an increase of $21.1 million or 70.0%. The growth in Shack sales was primarily driven by the opening of 15 new domestic company-operated Shacks between September 24, 2014 and September 30, 2015, as well as same-Shack sales growth of $3.6 million, or 17.1%. The increase in same-Shack sales is primarily due to increased guest traffic of 8.1% as well as a combined increase of 9.0% in price and sales mix. For purposes of calculating same-Shack sales growth, Shack sales for 16 Shacks were included in the comparable Shack base.

Shack sales were $133.9 million for the thirty-nine weeks ended September 30, 2015 compared to $79.0 million for the thirty-nine weeks ended September 24, 2014, an increase of $54.9 million or 69.5%. The increase is primarily due to the opening of 15 new domestic company-operated Shacks between September 24, 2014 and September 30, 2015, as well as same-Shack sales growth of $7.7 million, or 14.3%. The increase in same-Shack sales is primarily due to increased guest traffic of 5.2% as well as a combined increase of 9.1% in price and sales mix. For purposes of calculating same-Shack sales growth, Shack sales for 16 Shacks were included in the comparable Shack base.

Licensing Revenue

Licensing revenue is comprised of license fees and territory fees. License fees are calculated as a percentage of sales and territory fees are payments for the exclusive right to develop Shacks in a specific geographic area.

23

Licensing revenue was $2.0 million for the thirteen weeks ended September 30, 2015 compared to $1.7 million for the thirteen weeks ended September 24, 2014, an increase of $0.3 million or 20.4%. Licensing revenue was $5.6 million for the thirty-nine weeks ended September 30, 2015 compared to $4.8 million thirty-nine weeks ended September 24, 2014, an increase of $0.8 million or 17.9%. The increases for the thirteen and thirty-nine week periods were primarily driven by the opening of seven international licensed Shacks between September 24, 2014 and September 30, 2015.

Food and Paper Costs

Food and paper costs include the direct costs associated with food, beverage and packaging of our menu items. The components of food and paper costs are variable by nature, changing with sales volume, and are impacted by menu mix and fluctuations in commodity costs.

Food and paper costs were $14.9 million for the thirteen weeks ended September 30, 2015 compared to $9.3 million for the thirteen weeks ended September 24, 2014, an increase of $5.6 million or 59.8%. Food and paper costs were $39.7 million for thethirty-nine weeks ended September 30, 2015 compared to $24.2 million thirty-nine weeks ended September 24, 2014, an increase of $15.5 million or 63.5%. The increases for the thirteen and thirty-nine week periods were primarily due to the opening of 15 new domestic company-operated Shacks between September 24, 2014 and September 30, 2015.

As a percentage of Shack sales, food and paper costs decreased to 29.1% and 29.6% for the thirteen and thirty-nine weeks ended September 30, 2015, respectively, from 31.0% and 30.7% for the thirteen and thirty-nine weeks ended September 24, 2014, respectively. The decreases for the thirteen and thirty-nine week periods were primarily the result of menu price increases implemented in September 2014 and January 2015 and lower costs in certain ingredients such as dairy and fries, which were partially offset by slightly higher beef costs.

Labor and Related Expenses

Labor and related expenses include domestic company-operated Shack-level hourly and management wages, bonuses, payroll taxes, workers' compensation expense and medical benefits. As with other variable expenses, we expect labor costs to grow as we open more domestic company-operated Shacks. Other factors that influence labor costs include minimum wage and payroll tax legislation, health care costs and the performance of our domestic company-operated Shacks.

Labor and related expenses were $12.2 million for the thirteen weeks ended September 30, 2015 compared to $7.7 million for the thirteen weeks ended September 24, 2014, an increase of $4.5 million or 58.8%. Labor and related expenses were $32.4 million for the thirty-nine weeks ended September 30, 2015 compared to $20.6 million for the thirty-nine weeks ended September 24, 2014, an increase of $11.8 million or 57.5%. These increases for the thirteen and thirty-nine week periods were primarily due to the opening of 15 new domestic company-operated Shacks between September 24, 2014 and September 30, 2015.

As a percentage of Shack sales, labor and related expenses decreased to 23.7% and 24.2% for the thirteen and thirty-nine weeks ended September 30, 2015, respectively, compared to 25.4% and 26.1% for the thirteen and thirty-nine weeks ended September 24, 2014, respectively. The decreases for the thirteen and thirty-nine week periods were primarily due to the benefit from higher Shack sales and the reduced labor requirements from the return of crinkle-cut fries.

Other Operating Expenses

Other operating expenses consist of Shack-level marketing expenses, utilities and other operating expenses incidental to operating our domestic company-operated Shacks, such as non-perishable supplies, credit card fees, property insurance and the cost of repairs and maintenance.

Other operating expenses were $4.4 million for the thirteen weeks ended September 30, 2015 compared to $2.9 million for the thirteen weeks ended September 24, 2014, an increase of $1.5 million or 50.6%. Other operating expenses were $11.6 million for the thirty-nine weeks ended September 30, 2015 compared to $7.9 million for the thirty-nine weeks ended September 24, 2014, an increase of $3.7 million or 47.2%. The increases for the thirteen and thirty-nine week periods were primarily due to the opening of 15 new domestic company-operated Shacks between September 24, 2014 and September 30, 2015.

As a percentage of Shack sales, other operating expenses decreased to 8.5% and 8.6% for the thirteen and thirty-nine weeks ended September 30, 2015, respectively, compared to 9.6% and 10.0% for the thirteen and thirty-nine weeks ended September 24, 2014, respectively. The decrease was due to the benefit from higher Shack sales and the impact of fixed operating expenses on the higher sales levels.

Occupancy and Related Expenses

Occupancy and related expenses consist of Shack-level occupancy expenses including rent, common area expenses, real estate taxes and certain other local taxes. Occupancy costs incurred prior to the opening of a domestic company-operated Shack are recorded separately and included in pre-opening costs.

Occupancy and related expenses were $4.2 million for the thirteen weeks ended September 30, 2015 compared to $2.7 million for the thirteen weeks ended September 24, 2014, an increase of $1.5 million or 57.2%. Occupancy and related expenses were $11.2 million for the thirty-nine weeks ended

24

September 30, 2015 compared to $6.8 million or the thirty-nine weeks ended September 24, 2014, an increase of $4.4 million or 65.6%. The increases for the thirteen and thirty-nine week periods were primarily due to the opening of 15 new domestic company-operated Shacks between September 24, 2014 and September 30, 2015.

As a percentage of Shack sales, occupancy and related expenses decreased to 8.2% and 8.4% for the thirteen and thirty-nine weeks ended September 30, 2015, respectively, compared to 8.9% and 8.6% for the thirteen and thirty-nine weeks ended September 24, 2014, respectively. The decreases were primarily due to increased levels of Shack sales relative to fixed base rent and other occupancy expenses.

General and Administrative Expenses

General and administrative expenses consist of costs associated with corporate and administrative functions that support Shack development and operations, as well as equity-based compensation expense.

General and administrative expenses were $5.7 million for the thirteen weeks ended September 30, 2015 compared to $5.2 million for the thirteen weeks ended September 24, 2014, an increase of $0.5 million or 10.2%. The increase was primarily driven by incremental stock-based compensation expense related to the stock options granted in connection with our IPO, increased costs associated with becoming a public company and higher payroll expenses related to new home office personnel hired to support future growth. These increases were partially offset by the elimination of the management fees paid to USHG, as well as $1.5 million of IPO-related expenses incurred in the prior year for which none were incurred in the current year. As a percentage of total revenue, general and administrative expenses decreased to 10.8% for the thirteen weeks ended September 30, 2015 from 16.3% for the thirteen weeks ended September 24, 2014. This decrease was primarily due to the increased levels of Shack sales.

General and administrative expenses were $30.2 million for the thirty-nine weeks ended September 30, 2015 compared to $12.2 million for the thirty-nine weeks ended September 24, 2014, an increase of $18.0 million or 147.4%. As a percentage of total revenue, general and administrative expenses increased to 21.6% for the thirty-nine weeks ended September 30, 2015 compared to 14.6% for the thirty-nine weeks ended September 24, 2014. This increase was primarily due to $12.8 million of non-recurring compensation expenses incurred in connection with the vesting of equity awards upon consummation of our IPO, $0.6 million of incremental IPO-related expenses, incremental stock-based compensation expense related to the stock options granted in connection with our IPO, increased costs associated with becoming a public company and higher payroll expenses related to new home office personnel hired to support future growth. These were partially offset by the elimination of the management fees paid to USHG, as well as the aforementioned IPO-related expenses incurred in the prior year for which none were incurred in the current year.

Depreciation Expense

Depreciation expense consists of the depreciation of fixed assets, including leasehold improvements, equipment, furniture and fixtures and computer equipment and software.

Depreciation expense was $2.6 million for the thirteen weeks ended September 30, 2015 compared to $1.5 million for the thirteen weeks ended September 24, 2014, an increase of $1.1 million or 75.5%. Depreciation expense was $7.3 million for the thirty-nine weeks ended September 30, 2015 compared to $4.1 million for the thirty-nine weeks ended September 24, 2014, an increase of $3.2 million or 78.9%. The increases for the thirteen and thirty-nine week periods were due primarily to incremental depreciation of property and equipment related to the opening of 15 new domestic company-operated Shacks between September 24, 2014 and September 30, 2015.

As a percentage of total revenue, depreciation expense increased to 4.9% and 5.2% for the thirteen and thirty-nine weeks ended September 30, 2015, respectively, compared to 4.7% and 4.9% for the thirteen and thirty-nine weeks ended September 24, 2014, respectively, due to the introduction of more target-volume Shacks, which have lower sales volumes than our current company-wide average sales volume, despite similar build-out costs.

Pre-Opening Costs

Pre-opening costs primarily consist of legal fees, rent, managers' salaries, training costs, employee payroll and related expenses, costs to relocate and compensate Shack management teams prior to an opening and wages, travel and lodging costs for our opening training team and other supporting team members. All such costs incurred prior to the opening of a domestic company-operated Shack are expensed in the period in which the expense was incurred. Pre-opening costs can fluctuate significantly from period to period, based on the number and timing of domestic company-operated Shack openings and the specific pre-opening costs incurred for each domestic company-operated Shack. Additionally, domestic company-operated Shack openings in new geographic market areas will initially experience higher pre-opening costs than our established geographic market areas.

Pre-opening costs were $1.4 million for the thirteen weeks ended September 30, 2015, compared to $1.8 million for the thirteen weeks ended September 24, 2014, a decrease of $0.4 million or 20.7%. Pre-opening costs were $4.1 million for the thirty-nine weeks ended September 30, 2015 compared to $3.8 million for the thirty-nine weeks ended September 24, 2014, an increase of $0.3 million or 5.9%. The variances for the thirteen and thirty-nine week periods were due to the timing and total number of new domestic company-operated Shacks expected to open.

Loss on Disposal of Property and Equipment

Loss on disposal of property and equipment represents the net book value of assets that have been retired and consists primarily of furniture and fixtures that were replaced in the normal course of business.

For all periods presented, the loss on disposal of property and equipment was not material.

Interest Expense

Interest expense primarily consists of interest on our Revolving Credit Facility, as well as the amortization of deferred financing costs incurred in connection with the Revolving Credit Facility.

For all periods presented, interest expense was not material.

Income Tax Expense

Income tax expense was $1.5 million for the thirteen weeks ended September 30, 2015 compared to $0.1 million for the thirteen weeks ended September 24, 2014. Our effective income tax rate decreased to 19.8% for the thirteen weeks ended September 30, 2015 from 20.1% for the thirteen weeks ended September 24, 2014.

Income tax expense was $2.8 million for the thirty-nine weeks ended September 30, 2015 compared to $0.4 million for the thirty-nine weeks ended September 24, 2014. Our effective income tax rate increased to 97.3% for the thirty-nine weeks ended September 30, 2015 from 9.4% for the thirty-nine weeks ended September 24, 2014.

As a result of the IPO and Organizational Transactions, we became the sole managing member of SSE Holdings, which is treated as a partnership for U.S. federal and most applicable state and local income tax purposes. As a partnership, SSE Holdings is not subject to U.S. federal and certain state and local income taxes. Any taxable income or loss generated by SSE Holdings is passed through to and included in the taxable income or loss of its members, including us, on a pro rata basis. We are subject to U.S. federal income taxes, in addition to state and local income taxes with respect to our allocable share of any taxable income or loss generated by SSE Holdings subsequent to the Organizational Transactions. As the non-recurring compensation expenses and other IPO-related expenses were incurred in the period prior to the Organizational Transactions, we are not entitled to any tax benefits related to those expenses. We recognized tax expense on our allocable share of the pre-tax income subsequent to the Organizational Transactions, which results in a very high effective tax rate when compared to our consolidated pre-tax income for the thirty-nine weeks ended September 30, 2015. For the thirteen and thirty-nine weeks ended September 24, 2014, the reported income tax expense reflects that of SSE Holdings and relates solely to foreign withholding taxes and certain LLC entity-level taxes.

Shack-Level Operating Profit (Non-GAAP Financial Measure)

Shack-level operating profit and Shack-level operating profit margin are not required by, or presented in accordance with, GAAP. Shack-level operating profit is a supplemental measure of operating performance and our calculations thereof may not be comparable to similar measures reported by other companies. Shack-level operating profit margin has limitations as an analytical tool and should not be considered as a substitute for analysis of our results as reported under GAAP. We believe that Shack-level operating profit and Shack-level operating profit margin, when used in conjunction with GAAP financial measures, provide useful information about our operating results, enhance the overall understanding of past financial performance and future prospects, and allow for greater transparency with respect to key metrics used by us in our financial and operational decision making. Shack-level operating profit and Shack-level operating profit margin are important measures we use to evaluate the performance and profitability of each Shack, individually and in the aggregate. A reconciliation of Shack-level operating profit to operating income, the most directly comparable GAAP measure, is set forth below.

EBITDA and Adjusted EBITDA (Non-GAAP Financial Measures)

EBITDA and Adjusted EBITDA are non-GAAP supplemental measures of operating performance that do not represent and should not be considered alternatives to net income (loss) or cash flow from operations, as determined by GAAP. We use EBITDA and Adjusted EBITDA to measure the operating performance of our business, excluding specifically identified items that we don't believe directly reflect our core operations. A reconciliation of EBITDA and Adjusted EBITDA to net income, the most directly comparable GAAP measure, is set forth below.

	Thirteen Weeks Ended					Thirty-Nine Weeks Ended

Adjusted Pro Forma Net Income and Adjusted Pro Forma Earnings per Fully Exchanged and Diluted Share (Non-GAAP Financial Measures)

Adjusted pro forma net income represents net income attributable to Shake Shack Inc. assuming the full exchange of all outstanding LLC Interests for shares of Class A common stock, adjusted for certain non-recurring items that we don't believe directly reflect our core operations. Adjusted pro forma earnings per fully exchanged and diluted share is calculated by dividing adjusted pro forma net income by the weighted-average shares of Class A common stock outstanding, assuming the full exchange of all outstanding LLC Interests, after giving effect to the dilutive effect of outstanding stock options.

Adjusted pro forma net income and adjusted pro forma earnings per fully exchanged and diluted share are supplemental measures of operating performance that do not represent and should not be considered alternatives to net income and earnings per share, as determined by GAAP. We believe adjusted pro forma net income and adjusted pro forma earnings per fully exchanged and diluted share supplement GAAP measures and enable us to more effectively evaluate our performance period-over-period and relative to our competitors. A reconciliation of adjusted pro forma net income to net income (loss) attributable to Shake Shack Inc., the most directly comparable GAAP measure, and the computation of adjusted pro forma earnings per fully exchanged and diluted share are set forth below.

(3) Costs incurred in connection with our IPO, including legal, accounting and other related expenses.

(4) Represents the tax effect of the aforementioned adjustments and pro forma adjustments to reflect corporate income taxes at assumed effective tax rates of 43.3% and 44.0% for the thirteen and thirty-nine weeks ended September 30, 2015, respectively, and 41.6% and 44.4% for the and thirteen and thirty-nine weeks endedSeptember 24, 2014, respectively. Amounts include provisions for U.S. federal income taxes, certain LLC entity-level taxes and foreign withholding taxes, assuming the highest statutory rates apportioned to each applicable state, local and foreign jurisdiction.

(5) Adjustment to give effect to (i) 5,750,000 shares issued to investors in our IPO and (ii) 339,306 shares issued to participants of the UAR Plan, both of which were not retrospectively applied in the computations of earnings per share for the thirteen and thirty-nine weeks endedSeptember 24, 2014.

LIQUIDITY AND CAPITAL RESOURCES

Sources and Uses of Cash

Our primary sources of liquidity are cash from operations, cash on hand, and availability under our Revolving Credit Facility. As of September 30, 2015, we maintained a cash balance of $69.8 million and had $19.9 million of availability under our Revolving Credit Facility.

Our primary requirements for liquidity are to fund our working capital needs, operating lease obligations, capital expenditures and general corporate needs. Our requirements for working capital are not significant because our guests pay for their food and beverage purchases in cash or on debit or credit cards at the time of the sale and we are able to sell many of our inventory items before payment is due to the supplier of such items. Our ongoing capital expenditures are principally related to opening new Shacks, existing Shack capital investments (both for remodels and maintenance), as well as investments in our corporate infrastructure.

In addition, we are obligated to make payments to the Continuing SSE Equity Owners under the Tax Receivable Agreement. As of September 30, 2015, such obligations totaled $92.4 million. Although the amount of any payments that must be made under the Tax Receivable Agreement may be significant, the timing of these payments will vary and will generally be limited to one payment per member per year. The amount of such payments are also limited to the extent we utilize the related deferred tax assets. The payments that we are required to make will generally reduce the amount of overall cash that might have otherwise been available to us or to SSE Holdings, but we expect the cash tax savings we will realize from the utilization of the related deferred tax assets to fund the required payments.

We believe that cash provided by operating activities, cash on hand and availability under the Revolving Credit Facility will be sufficient to fund our operating lease obligations, capital expenditures, tax receivable agreement obligations and working capital needs for at least the next 12 months and the foreseeable future.

Summary of Cash Flows

The following table presents a summary of our cash flows from operating, investing and financing activities.

	Thirty-Nine Weeks Ended
	September 30, 2015			September 24, 2014
Net cash provided by operating activities	$	30,943		$	11,433
Net cash used in investing activities	(25,327		)	(17,885		)
Net cash provided by (used in) financing activities	61,528			(517		)
Increase (decrease) in cash	67,144			(6,969		)
Cash at beginning of period	2,677			13,076
Cash at end of period	$	69,821		$	6,107

Operating Activities

For the thirty-nine weeks ended September 30, 2015 net cash provided by operating activities was $30.9 million compared to $11.4 million for the thirty-nine weeks ended September 24, 2014, an increase of $19.5 million. This increase was primarily driven by the opening of 15 new domestic company-operated Shacks.

Investing Activities

For the thirty-nine weeks ended September 30, 2015 net cash used in investing activities was $25.3 million compared to $17.9 million for the thirty-nine weeks ended September 24, 2014, an increase of $7.4 million. This increase was due to an increase in capital expenditures to construct new domestic company-operated Shacks in such period compared to the same period in fiscal 2014.

Financing Activities

For the thirty-nine weeks ended September 30, 2015, net cash provided by financing activities was $61.5 million compared to net cash used in financing activities of $0.5 million for the thirty-nine weeks ended September 24, 2014, an increase of $62.0 million. This increase is primarily due to $109.4 million of net proceeds received from the IPO, offset by $36.0 million in payments on the Revolving Credit Facility, an increase in member distributions of $5.9 million and payments of employee withholding taxes of $4.6 million related to net settled equity awards.

Revolving Credit Facility

In January 2015, we executed a Third Amended and Restated Credit Agreement, which became effective on February 4, 2015 (together with the prior agreements and amendments, the "Revolving Credit Facility"), which provides for a revolving total commitment amount of $50.0 million, of which $20.0 million is available immediately. The Revolving Credit Facility will mature and all amounts outstanding will be due and payable five years from the effective date. The Revolving Credit Facility permits the issuance of letters of credit upon our request of up to $10.0 million. Borrowings under the Revolving Credit Facility bear interest at either: (i) LIBOR plus a percentage ranging from 2.5% to 3.5% or (ii) the prime rate plus a percentage ranging from 0.0% to 1.0%, depending on the type of borrowing made under the Revolving Credit Facility. As of December 31, 2014, amounts outstanding under the Revolving Credit Facility totaled $32.0 million, and were classified as short-term borrowings on the Condensed Consolidated Balance Sheets. During the thirty-nine weeks ended September 30, 2015, we borrowed an additional $4.0 million in principal under the Revolving Credit Facility. In February 2015, we repaid the entire outstanding balance of $36.0 million using a portion of the proceeds we received from our IPO, and as of September 30, 2015, there were no amounts outstanding under the Revolving Credit Facility. We had $19.9 million of availability as of September 30, 2015, after giving effect to $0.1 million in outstanding letters of credit.

The Revolving Credit Facility is secured by a first-priority security interest in substantially all of the assets of SSE Holdings and the guarantors. The obligations under the Revolving Credit Facility are guaranteed by each of SSE Holdings' wholly-owned domestic subsidiaries (with certain exceptions).

The Revolving Credit Facility contains a number of covenants that, among other things, restrict our ability to, subject to specified exceptions, incur additional debt; incur additional liens and contingent liabilities; sell or dispose of assets; merge with or acquire other companies; liquidate or dissolve ourselves; pay dividends or make distributions; engage in businesses that are not in a related line of business; make loans, advances or guarantees; engage in transactions with affiliates; and make investments. In addition, the Revolving Credit Facility contains certain cross-default provisions. We are required to maintain a specified consolidated fixed-charge coverage ratio and a specified funded net debt to adjusted EBITDA ratio, both as defined under the Revolving Credit Facility. As of September 30, 2015, we were in compliance with all covenants.

CONTRACTUAL OBLIGATIONS

There have been no material changes to the contractual obligations as disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014, other than those made in the ordinary course of business.

OFF-BALANCE SHEET ARRANGEMENTS

There has been no material change in our off-balance sheet arrangements discussed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014.

CRITICAL ACCOUNTING POLICIES

Our discussion and analysis of our consolidated financial condition and results of operations is based upon the accompanying condensed consolidated financial statements and notes thereto, which have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP"). The preparation of the condensed consolidated financial statements requires us to make estimates, judgments and assumptions, which we believe to be reasonable, based on the information available. These estimates and assumptions affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities. Variances in the estimates or assumptions used to actual experience could yield materially different accounting results. On an ongoing basis, we evaluate the continued appropriateness of our accounting policies and resulting estimates to make adjustments we consider appropriate under the facts and circumstances. There have been no significant changes to our critical accounting policies as disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014.

Recently Issued Accounting Pronouncements

In August 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2015-15, Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements ("ASU 2015-15"), which clarifies the guidance set forth in Accounting Standards Update No. 2015-03, Simplifying the Presentation of Debt Issuance Costs ("ASU 2015-03"), issued in April 2015. ASU 2015-03 requires that debt issuance costs related to a recognized liability be presented on the balance sheet as a direct reduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected. ASU 2015-15 provides additional guidance regarding debt issuance costs associated with line-of-credit arrangements, stating that the SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred issuance costs ratably over the term of the line-of-credit arrangement. ASU 2015-03 is effective for reporting periods beginning after December 15, 2015. The adoption of ASU 2015-03 and ASU 2015-15 is not expected to have a material effect our consolidated financial position, results of operations or cash flows.

In April 2015, the FASB issued Accounting Standards Update No. 2015-05, Customers' Accounting for Fees Paid in a Cloud Computing Arrangement ("ASU 2015-05"). ASU 2015-05 provides guidance in evaluating whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the software license element of the arrangement should be accounted for as an acquisition of a software license. If the arrangement does not contain a software license, it should be accounted for as a service contract. ASU 2015-05 is effective for reporting periods beginning after December 15, 2015 and may be adopted either retrospectively or prospectively. We are currently evaluating the impact ASU 2015-05 will have on our consolidated financial statements.

In April 2015, the FASB issued Accounting Standards Update No. 2015-03, Simplifying the Presentation of Debt Issuance Costs ("ASU 2015-03"). ASU 2015-03 requires that debt issuance costs related to a recognized liability be presented on the balance sheet as a direct reduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected. ASU 2015-03 is effective for reporting periods beginning after December 15, 2015. The adoption of ASU 2015-03 is not expected to have a material effect our consolidated financial position, results of operations or cash flows.

In February 2015, the FASB issued Accounting Standards Update No. 2015-02, Consolidation ("ASU 2015-02"). ASU 2015-02 amends the existing guidance to: (i) modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities (VIEs) or voting interest entities; (ii) eliminate the presumption that a general partner should consolidate a limited partnership; (iii) affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships and (iv) provide a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. ASU 2015-02 is effective for reporting periods beginning after December 15, 2015. We are currently evaluating the impact ASU 2015-02 will have on our consolidated financial statements.

In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"). ASU 2014-09 supersedes the existing revenue recognition guidance and clarifies the principles for recognizing revenue. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. In August 2015, the FASB issued an update to ASU 2014-09 deferring the effective date for public entities, on a retrospective basis, to annual reporting periods beginning after December 15, 2017. Early adoption is permitted, subject to certain conditions. We are currently evaluating the impact ASU 2014-09 will have on our consolidated financial position, results of operations and cash flows.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

There have been no material changes to our exposure to market risks as described in Part II, Item 7A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2014.

Item 4. Controls and Procedures.

DISCLOSURE CONTROLS AND PROCEDURES

Under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of such date. Our disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms and that such information is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

USE OF PROCEEDS

Initial Public Offering

On January 29, 2015, our Registration Statement on Form S-1 (File No. 333-201271) was declared effective by the SEC for our IPO pursuant to which we registered and sold an aggregate of 5,750,000 shares of our Class A common stock (including 750,000 shares sold pursuant to the underwriters' over-allotment option) at a price of $21.00 per share. J.P. Morgan Securities LLC and Morgan Stanley & Co. LLC acted as joint lead book-running managers in the offering. Barclays Capital Inc., Goldman, Sachs & Co., and Jefferies LLC also acted as book-running managers in the offering. William Blair & Company, LLC and Stifel acted as co-managers in the offering. The offering commenced on January 29, 2015 and did not terminate before all of the securities registered in the registration statement were sold. The offering closed on February 4, 2015, resulting in net proceeds of $106.1 million after deducting underwriters' discounts and commissions of $8.5 million and other offering expenses of $6.2 million. No payments were made by us to directors, officers or persons owning 10% or more of our common stock or to their associates, or to our affiliates. 

We used the net proceeds to us from the IPO to purchase 5,750,000 newly-issued LLC Interests from SSE Holdings at a purchase price per interest equal to the initial public offering price per share of Class A common stock.

As sole managing member of SSE Holdings, we caused SSE Holdings to use the proceeds it received as follows: (i) to pay fees and expenses of approximately $6.2 million in connection with the IPO and the Organizational Transactions, (ii) to repay the outstanding borrowings under our Revolving Credit Facility of approximately $36.0 million, including approximately $21.9 million of borrowings used to pay a distribution to certain of the Original SSE Equity Owners prior to the offering; (iii) to pay an additional distribution in the amount of $11.1 million to certain of the Original SSE Equity Owners; and (iv) approximately $59.0 million for general corporate purposes, including opening new Shacks and renovating existing Shacks.

The $11.1 million additional distribution paid by SSE Holdings to certain of the Original SSE Equity Owners include direct payments to certain directors, executive officers and beneficial owners of 10% or more of our common stock.

There has been no material change in the use of proceeds as described in the final prospectus filed with the SEC on January 30, 2015.

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 affiliates of the Former SSE Equity Owners and certain of the Continuing SSE Equity Owners (the "Selling Stockholders"). We did not receive any proceeds from the sale of shares of Class A common stock offered by the Selling Stockholders. The shares sold in the offering consisted of (i) 844,727 existing shares of Class A common stock held by the Former SSE Equity Owners 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 Continuing SSE Equity Owners that participated in the offering. Simultaneously, and in connection with the redemption, 3,155,273 shares of Class B common stock were surrendered by the Continuing SSE Equity Owners and canceled. Additionally, in connection with the redemption, we received 3,155,273 newly-issued LLC Interests, increasing our total ownership interest in SSE Holdings.
