NOTE 1: 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 ("SSE Holdings"). We are the sole managing member of SSE Holdings and, as sole managing member, we operate and control all of the business and affairs of SSE Holdings. As a result, we consolidate the financial results of SSE Holdings and report a non-controlling interest representing the economic interest in SSE Holdings held by the other members of SSE Holdings. As of March 31, 2021 we owned 93.0% of SSE Holdings. Unless the context otherwise requires, "we," "us," "our," "Shake Shack," the "Company" and other similar references, refer to Shake Shack Inc. and, unless otherwise stated, all of its subsidiaries, including 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 March 31, 2021, there were 321 Shacks in operation, system-wide, of which 192 were domestic Company-operated Shacks, 22 were domestic licensed Shacks and 107 were international licensed Shacks. As of March 31, 2021, four domestic Company-operated Shacks and 16 licensed Shacks were temporarily closed, primarily due to the COVID-19 pandemic.

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 30, 2020 ("2020 Form 10-K"). Certain information and footnote disclosures normally presented in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. These interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes thereto included in our 2020 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. Operating results for interim periods are not necessarily indicative of the results that may be expected for a full fiscal year.

SSE Holdings is considered a variable interest entity. Shake Shack Inc. is the primary beneficiary as we have the majority economic interest in SSE Holdings and, as the sole managing member, have decision making authority that significantly affects the economic performance of the entity, while the limited partners have no substantive kick-out or participating rights. As a result, we consolidate SSE Holdings. The assets and liabilities of SSE Holdings represent substantially all of our consolidated assets and liabilities with the exception of certain deferred taxes and liabilities under the Tax Receivable Agreement. As of March 31, 2021 and December 30, 2020, the net assets of SSE Holdings were $380,713 and $383,669, respectively. The assets of SSE Holdings are subject to certain restrictions in SSE Holdings' revolving credit agreement. See Note 6, Debt, for more information.

Fiscal Year

We operate on a 52/53 week fiscal year ending on the last Wednesday in December. Fiscal 2021 contains 52 weeks and ends on December 29, 2021. Fiscal 2020 contained 53 weeks and ended on December 30, 2020. 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 management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and

Table of Contents

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 Adopted Accounting Pronouncements   

We adopted the Accounting Standards Updates (“ASUs”) summarized below in fiscal 2021.

Accounting Standards Update			Description			Date Adopted
Simplifying the Accounting for Income Taxes (ASU 2019-12)			This standard simplifies various aspects related to accounting for income taxes by removing certain exceptions to the general principles in ASC 740, “Income Taxes” (“ASC 740”), and clarifying certain aspects of the current guidance to promote consistency among reporting entities. The adoption of this standard did not have a material impact to our condensed consolidated financial statements.			December 31, 2020
Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity's Own Equity (Subtopic 815-40)—Accounting For Convertible Instruments and Contracts in an Entity's Own Equity. (ASU 2020-06)			This ASU amends the guidance on convertible instruments and the derivatives scope exception for contracts in an entity’s own equity and improves and amends the related earnings per share guidance for both Subtopics. We elected to early adopt this standard, beginning December 31, 2020. The guidance of this ASU is applicable to our convertible notes issued in March 2021. As a result, the convertible notes are accounted for as a single liability measured at amortized cost. The if-converted earnings per share ("EPS") method is used, with the effect of potential share settlement included in diluted EPS. Refer to Note 6, Debt, for further details of the convertible notes issued.			December 31, 2020

NOTE 3: REVENUE

Revenue Recognition

Revenue consists of Shack sales and Licensing revenue. Generally, revenue is recognized as promised goods or services transfer to the guest or customer in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Shack revenues are recognized when payment is tendered at the point of sale as the performance obligation has been satisfied.

Revenue from Shack sales is presented net of discounts and recognized when food, beverage and retail products are sold. Sales tax collected from customers is excluded from Shack sales and the obligation is included in sales tax payable until the taxes are remitted to the appropriate taxing authorities. Revenue from our gift cards is deferred and recognized upon redemption.

Licensing revenues include initial territory fees, Shack opening fees, and ongoing sales-based royalty fees from licensed Shacks. Generally, the licenses granted to develop, open and operate each Shack in a specified territory are the predominant goods or services transferred to the licensee in our contracts, and represent distinct performance obligations. Ancillary promised services, such as training and assistance during the initial opening of a Shack, are typically combined with the licenses and considered as one performance obligation per Shack. We determine the transaction price for each contract, which is comprised of the initial territory fee, and an estimate of the total Shack opening fees we expect to be entitled to. The calculation of total Shack opening fees included in the transaction price requires judgment, as it is based on an estimate of the number of Shacks we expect the licensee to open. The transaction price is then allocated equally to each Shack expected to open. The performance obligations are satisfied over time, starting when a Shack opens, through the end of the term of the license granted to the Shack. Because we are transferring licenses to access our intellectual property during a contractual term, revenue is recognized on a straight-line basis over the license term. Generally, payment for the initial territory fee is received upon execution of the licensing agreement, and payment for the Shack opening fees are received either in advance of or upon opening the related Shack. These payments are initially deferred and recognized as revenue as the performance obligations are satisfied, which occurs over a long-term period.

Table of Contents

Revenue from sales-based royalties is recognized as the related sales occur.

Revenue recognized during the thirteen weeks ended March 31, 2021 and March 25, 2020, disaggregated by type is as follows:

			Thirteen Weeks Ended
			March 31 2021						March 25 2020
Shack sales			$	150,668					$	138,048
Licensing revenue:
Sales-based royalties			4,425						4,944
Initial territory and opening fees			189						178
Total revenue			$	155,282					$	143,170

The aggregate amount of the transaction price allocated to performance obligations that are unsatisfied (or partially unsatisfied) as of March 31, 2021 was $16,748. We expect to recognize this amount as revenue over a long-term period, as the license term for each Shack ranges from 5 to 20 years. This amount excludes any variable consideration related to sales-based royalties.

Contract Balances

Opening and closing balances of contract liabilities and receivables from contracts with customers is as follows:

						March 31 2021						December 31 2020
Shack sales receivables						$	5,641					$	5,373
Licensing receivables, net of allowance for doubtful accounts						2,420						2,647
Gift card liability						2,600						2,637
Deferred revenue, current						612						608
Deferred revenue, long-term						11,965						12,151

Revenue recognized during the thirteen weeks ended March 31, 2021 and March 25, 2020 that was included in their respective liability balances at the beginning of the period is as follows:

			Thirteen Weeks Ended
			March 31 2021						March 25 2020
Gift card liability			$	219					$	300
Deferred revenue			181						175

The carrying value of our Cash and cash equivalents, Accounts receivable, net, Accounts payable and Accrued expenses approximate their fair value due to the short-term nature of these financial instruments.

As of March 31, 2021 and December 30, 2020, we held certain assets that are required to be measured at fair value on a recurring basis including our Marketable securities, which consist of investments in equity securities. Fair value of these investments is measured using Level 1 inputs (unadjusted quoted prices in active markets for identical assets). The carrying value of these investments in equity securities approximates fair value.

Our assets measured at fair value on a recurring basis as of March 31, 2021 and December 30, 2020 were as follows:

Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis

Assets and liabilities that are measured at fair value on a non-recurring basis include our long-lived assets, operating lease right-of-use assets and indefinite-lived intangible assets. During the thirteen weeks ended March 25, 2020, we recognized an impairment charge of $1,132 at one location. Of the total impairment charge, $736 was attributed to property and equipment held and used, $383 was attributed to operating lease right-of-use assets, and $13 was attributed to finance lease right-of-use assets. The asset impairment charge was included in Impairment and loss on disposal of assets on the Condensed Consolidated Statement of Income (Loss). The fair values of assets were determined using an income-based approach and are classified as Level 3 within the fair value hierarchy. Significant inputs include projections of future cash flows, discount rates, Shack sales and profitability. There were no impairment charges recognized during the thirteen weeks ended March 31, 2021.

NOTE 6: DEBT

Revolving Credit Facility

In August 2019, we entered into a revolving credit facility agreement ("Revolving Credit Facility"), which permits borrowings up to $50,000, of which the entire amount is available immediately, with the ability to increase available borrowings up to an additional $100,000, to be made available subject to satisfaction of certain conditions. The Revolving Credit Facility also permits the issuance of letters of credit upon our request of up to $15,000.

In March 2020, we drew down the full $50,000 available under the Revolving Credit Facility to enhance liquidity and financial flexibility given the uncertain market conditions created by the COVID-19 pandemic. We repaid this amount in full, plus interest, in June 2020.

In May 2020, we entered into a first amendment to the Revolving Credit Facility ("First Amendment"), which, among other things, provided for modified financial covenant compliance requirements for a period of time. The First Amendment required us to maintain minimum liquidity of $25,000 through July 1, 2021 and outstanding borrowings during the applicable period covered by the First Amendment bore interest at either: (i) the London Interbank Offered Rate ("LIBOR") plus a percentage ranging from 1.0% to 2.5% or (ii) the base rate plus a percentage ranging from 0.0% to 1.5%, in each case depending on our net lease adjusted leverage ratio.

In March 2021, we entered into a second amendment to the Revolving Credit Facility (“Second Amendment”). The Second Amendment modified the applicable covenants and restrictions in the Credit Agreement to permit the incurrence of the Convertible Notes (as defined below), including obligations and transactions in connection therewith. In addition, the Second Amendment, among other things, (i) extended the period applicable to the increased interest rate margin as set forth in the First Amendment; (ii) shortened the maturity date of the Revolving Credit Facility from August 2024 to September 2022 and (iii) added mechanics relating to the transition from the use of LIBOR to the Secured Overnight Financing Rate ("SOFR") upon the discontinuance or unavailability of LIBOR.

Subsequently, and also in March 2021, we entered into a third amendment to the Revolving Credit Facility (“Third Amendment”) with JPMorgan Chase Bank, N.A. (as successor agent to Wells Fargo Bank, National Association), as administrative agent, and

Shake Shack Inc. Form 10-Q | 13

Table of Contents

the lenders party thereto. In addition, in March 2021, Wells Fargo Bank resigned as administrative agent under the Revolving Credit Facility and assigned its commitments thereunder to JPMorgan Bank, N.A. The Third Amendment appoints JPMorgan Bank, N.A. as administrative agent under the Revolving Credit Facility. In addition, the Third Amendment, among other things, extends the maturity date of the Revolving Credit Facility from September 2022 to March 2026. As of March 31, 2021 and December 30, 2020, no amounts were outstanding under the Revolving Credit Facility.

The obligations under the Revolving Credit Facility are 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' direct and indirect subsidiaries (with certain exceptions).

The Revolving Credit Facility requires us to comply with maximum net lease adjusted leverage and minimum fixed charge coverage ratios. We are not subject to these coverage ratios for a period of time due to the Second Amendment to the Revolving Credit Facility described above. In addition, the Revolving Credit Facility contains other customary affirmative and negative covenants, including those which (subject to certain exceptions and dollar thresholds) limit our ability to incur debt; incur liens; make investments; engage in mergers, consolidations, liquidations or acquisitions; dispose of assets; make distributions on or repurchase equity securities; engage in transactions with affiliates; and prohibits us, with certain exceptions, from engaging in any line of business not related to our current line of business. As of March 31, 2021, we were in compliance with all covenants.

As of March 31, 2021, the Revolving Credit Facility had unamortized deferred financing costs of $110, and was included in Other assets on the Condensed Consolidated Balance Sheet. Total interest expense related to the Revolving Credit Facility were $368 and $52 for the thirteen weeks ended March 31, 2021 and March 25, 2020, respectively. Total interest expense for the thirteen weeks ended March 31, 2021 primarily included write-off of previously capitalized costs on the Revolving Credit Facility.

Convertible Notes

In March 2021, we issued $225,000 aggregate principal amount of 0% Convertible Senior Notes due 2028 (the “Convertible Notes”) in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933. We granted an option to the initial purchasers to purchase up to an additional $25,000 aggregate principal amount of Convertible Notes to cover over-allotments, which was subsequently fully exercised during March 2021, resulting in a total issuance of $250,000 aggregate principal amount of Convertible Notes. The Convertible Notes will mature on March 1, 2028, unless earlier converted, redeemed or repurchased in certain circumstances. Upon conversion, we pay or deliver, as the case may be, cash, shares of Shake Shack’s Class A common stock or a combination of cash and shares of Shake Shack’s Class A common stock, at our election.

The Convertible Notes are convertible at the option of the holders at any time prior to the close of business on the business day immediately preceding December 1, 2027, only under the following circumstances: (1) during any fiscal quarter commencing after the fiscal quarter ending on June 30, 2021 (and only during such fiscal quarter), if the last reported sale price of our Class A common stock, par value $0.001 per share, for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price for the Convertible Notes on each applicable trading day; (2) during the five business day period after any ten consecutive trading day period (the “measurement period”) in which the trading price (as defined in the Indenture) per $1,000 principal amount of the Convertible Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of Class A common stock and the conversion rate for the Convertible Notes on each such trading day; (3) if we call such Convertible Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date, but only with respect to the Convertible Notes called (or deemed called) for redemption; and (4) upon the occurrence of specified corporate events as set forth in the Indenture. On or after December 1, 2027, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders of the Convertible Notes may convert all or any portion of their Convertible Notes at any time, regardless of the foregoing circumstances.

The Convertible Notes had an initial conversion rate of 5.8679 shares of Shake Shack’s Class A common stock per $1,000 principal amount of Convertible Notes, which is equivalent to an initial conversion price of approximately $170.42 per share of Shake Shack’s Class A common stock.

We may not redeem the Convertible Notes prior to March 6, 2025. We may redeem for cash all or any portion of the Convertible Notes, at our option, on or after March 6, 2025 if the last reported sale price of Shake Shack’s Class A common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30

consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption at a redemption price equal to 100% of the principal amount of the Convertible Notes to be redeemed, plus accrued and unpaid special interest, if any, to, but excluding, the redemption date.

In addition, if we undergo a fundamental change (as defined in the indenture governing the Convertible Notes), subject to certain conditions, holders may require us to repurchase for cash all or any portion of their Convertible Notes at a repurchase price equal to 100% of the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid special interest, if any, to, but excluding, the fundamental change repurchase date. In addition, following certain corporate events that occur prior to the maturity date of the Convertible Notes or if we deliver a notice of redemption in respect of some or all of the Convertible Notes, we will, in certain circumstances, increase the conversion rate of the Convertible Notes for a holder who elects to convert our Convertible Notes in connection with such a corporate event or convert our Convertible Notes called (or deemed called) for redemption during the related redemption period, as the case may be.

Contemporaneously with the issuance of the Convertible Notes, Shake Shack Inc. entered into an intercompany note with SSE Holdings, LLC (“Intercompany Note”). SSE Holdings promises to pay Shake Shack, Inc., for value received, the principal amount with interest of the Intercompany Note in March 2028. Shake Shack Inc. will exercise its right to convert the Intercompany Note to maintain at all times a one-to-one ratio between the number of common units, directly or indirectly, by Shake Shack Inc and the aggregate number of outstanding shares of common stock.

As of March 31, 2021, the Convertible Notes had a gross principal balance of $250,000 and a balance of $242,875, net of unamortized discount and debt issuance costs of $7,125. As of March 31, 2021, the unamortized balance of discount and debt issuance costs was recorded as a contra-liability and netted with Long-term debt on the Condensed Consolidated Balance Sheets and was being amortized as interest expense using the effective interest method. Total amortization expense was $86 for the thirteen weeks ended March 31, 2021 and was included in Interest expense in the Condensed Consolidated Statements of Income (Loss). In connection with the Convertible Notes, we also incurred costs of $236, including consulting and advisory fees, in the thirteen weeks ended March 31, 2021 and was included in General and administrative expense in the Condensed Consolidated Statements of Income (Loss).

At March 31, 2021, the fair value of the Convertible Notes was approximately $248,125, based on external pricing data, including available quoted market prices of these instruments, and consideration of comparable debt instruments with similar interest rates and trading frequency, among other factors, and is classified as a Level 2 measurement within the fair value hierarchy.

NOTE 7: LEASES

Nature of Leases

We currently lease all of our domestic Company-operated Shacks, our home office and certain equipment under various non-cancelable lease agreements that expire on various dates through 2037. We evaluate contracts entered into to determine whether the contract involves the use of property or equipment, which is either explicitly or implicitly identified in the contract. We evaluate whether we control the use of the asset, which is determined by assessing whether we obtain substantially all economic benefits from the use of the asset, and whether we have the right to direct the use of the asset. If these criteria are met and we have identified a lease, we account for the contract under the requirements of Accounting Standards Codification Topic 842 ("ASC 842").

Upon the possession of a leased asset, we determine its classification as an operating or finance lease. Our real estate leases are classified as operating leases and most of our equipment leases are classified as finance leases. Generally, our real estate leases have initial terms ranging from 10 to 15 years and typically include two five-year renewal options. Renewal options are generally not recognized as part of the right-of-use assets and lease liabilities as it is not reasonably certain at commencement date that we would exercise the options to extend the lease. Our real estate leases typically provide for fixed minimum rent payments and/or contingent rent payments based upon sales in excess of specified thresholds. When the achievement of such sales thresholds are deemed to be probable, contingent rent is accrued in proportion to the sales recognized during the period. Fixed minimum rent payments are recognized on a straight-line basis over the lease term from the date we take possession of the leased property. Lease expense incurred before a Shack opens is recorded in Pre-opening costs on the Condensed Consolidated Statements of Income (Loss). Once a domestic Company-operated Shack opens, we record the straight-line lease

Shake Shack Inc. Form 10-Q | 15

Table of Contents

expense and any contingent rent, if applicable, in Occupancy and related expenses on the Condensed Consolidated Statements of Income (Loss). Many of our leases also require us to pay real estate taxes, common area maintenance costs and other occupancy costs which are included in Occupancy and related expenses on the Condensed Consolidated Statements of Income (Loss).

As there are no explicit rates provided in our leases, we use our incremental borrowing rate in determining the present value of future lease payments. The discount rate used to measure the lease liability is derived from the average of the yield curves obtained from using the notching method and the recovery rate method. The most significant assumption in calculating the incremental borrowing rate is our credit rating and is subject to judgment. We determined our credit rating based on a comparison of the financial information of SSE Holdings to other public companies and then used their respective credit ratings to develop our own.

We expend cash for leasehold improvements to build out and equip our leased premises. Generally, a portion of the leasehold improvements and building costs are reimbursed by our landlords as landlord incentives pursuant to agreed-upon terms in our lease agreements. If obtained, landlord incentives usually take the form of cash, full or partial credits against our future minimum or contingent rents otherwise payable by us, or a combination thereof. In most cases, landlord incentives are received after we take possession of the property, as we meet required milestones during the construction of the property. We include these amounts in the measurement of the initial operating lease liability, which are also reflected as a reduction to the initial measurement of the right-of-use asset.

A summary of finance and operating lease right-of-use assets and liabilities as of March 31, 2021 and December 30, 2020 is as follows:

			Classification			March 31 2021						December 30 2020

NOTE 8: NON-CONTROLLING INTERESTS

We are the sole managing member of SSE Holdings and, as a result, consolidate the financial results of SSE Holdings. We report a non-controlling interest representing the economic interest in SSE Holdings held by the other members of SSE Holdings. The Third Amended and Restated Limited Liability Company Agreement, as further amended, (the "LLC Agreement") of SSE Holdings 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. In connection with any redemption or

exchange, we will receive a corresponding number of LLC Interests, increasing our total ownership interest in SSE Holdings. Changes in our ownership interest in SSE Holdings while we retain our controlling interest in SSE Holdings will be accounted for as equity transactions. As such, future redemptions or direct exchanges of LLC Interests in SSE Holdings by the other members of SSE Holdings will result in a change in ownership and reduce the amount recorded as non-controlling interest and increase additional paid-in capital.

The following table summarizes the ownership interest in SSE Holdings as of March 31, 2021 and December 30, 2020.

			March 31, 2021												December 30, 2020
			LLC Interests						Ownership%						LLC Interests						Ownership %

Total LLC Interests outstanding			42,024,827						100.0		%				41,668,978						100.0		%

The weighted average ownership percentages for the applicable reporting periods are used to attribute Net income (loss) and Other comprehensive income (loss) to Shake Shack Inc. and the non-controlling interest holders. The non-controlling interest holders' weighted average ownership percentage for the thirteen weeks ended March 31, 2021 and March 25, 2020 was 7.0% and 8.4%, respectively.

NOTE 10: INCOME TAXES

We are the sole managing member of SSE Holdings and, as a result, consolidate the financial results of SSE Holdings. SSE Holdings 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, as well as any stand-alone income or loss generated by Shake Shack Inc. We are also subject to withholding taxes in foreign jurisdictions.

Our effective income tax rates for the thirteen weeks ended March 31, 2021 and March 25, 2020 were 105.5% and (8.8)%, respectively. The increase was primarily driven by lower pre-tax book income resulting in a loss, causing tax credits and windfall tax benefits related to equity-based compensation to have an increasing effect on the tax rate, as well as a reduction of a valuation allowance. Additionally, an increase in our ownership interest in SSE Holdings increases our share of the taxable income (loss) of SSE Holdings. Our weighted-average ownership interest in SSE Holdings was 93.0% and 91.6% for the thirteen weeks ended March 31, 2021 and March 25, 2020, respectively.

Deferred Tax Assets and Liabilities

During the thirteen weeks ended March 31, 2021, we acquired an aggregate of 385,449 LLC Interests in connection with the redemption of LLC Interests, and activity relating to our stock compensation plan. We recognized a deferred tax asset in the amount of $10,204 associated with the basis difference in our investment in SSE Holdings upon acquisition of these LLC Interests. As of March 31, 2021, the total deferred tax asset related to the basis difference in our investment in SSE Holdings was $142,867. However, a portion of the total basis difference will only reverse upon the eventual sale of our interest in SSE Holdings, which we expect would result in a capital loss. As of March 31, 2021, the total valuation allowance established against the deferred tax asset to which this portion relates was $1,260.

Shake Shack Inc. Form 10-Q | 19

Table of Contents

During the thirteen weeks ended March 31, 2021, we also recognized $300 of deferred tax assets related to additional tax basis increases generated from expected future payments under the Tax Receivable Agreement and related deductions for imputed interest on such payments. See "Tax Receivable Agreement," herein for more information.

We evaluate the realizability of our deferred tax assets on a quarterly basis and establish valuation allowances when it is more likely than not that all or a portion of a deferred tax asset may not be realized. As of March 31, 2021, we concluded, based on the weight of all available positive and negative evidence, that all of our deferred tax assets (except for those deferred tax assets described above relating to basis differences that are expected to result in a capital loss upon eventual sale of our interest in SSE Holdings, New York City UBT credits and certain foreign tax credits) are more likely than not to be realized. As such, no additional valuation allowance was recognized.

Tax Receivable Agreement

Pursuant to our election under Section 754 of the Internal Revenue Code (the "Code"), we expect to obtain an increase in our share of the tax basis in the net assets of SSE Holdings when LLC Interests are redeemed or exchanged by the other members of SSE Holdings. We plan to make an election under Section 754 of the Code for each taxable year in which a redemption or exchange of LLC Interest occurs. We intend to treat any redemptions and exchanges of LLC Interests as direct purchases of LLC Interests for U.S. federal income tax purposes. These increases in tax basis may reduce the amounts that we would otherwise pay in the future to various tax authorities. They 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 certain of the then-existing members of SSE Holdings (the "Tax Receivable Agreement") that provides for the payment by us of 85% of the amount of any tax benefits that we actually realize, or in some cases are deemed to realize, as a result of (i) increases in our share of the tax basis in the net assets of SSE Holdings resulting from any redemptions or exchanges of LLC Interests, (ii) tax basis increases attributable to payments made under the Tax Receivable Agreement, and (iii) deductions attributable to imputed interest pursuant to the Tax Receivable Agreement (the "TRA Payments"). We expect to benefit from the remaining 15% of any tax benefits that we may actually realize. The TRA Payments are not conditioned upon any continued ownership interest in SSE Holdings or us. The rights of each member of SSE Holdings that is a party to the Tax Receivable Agreement, are assignable to transferees of their respective LLC Interests.

During the thirteen weeks ended March 31, 2021, we acquired an aggregate of 29,600 LLC Interests in connection with the redemption of LLC Interests, which resulted in an increase in the tax basis of our investment in SSE Holdings subject to the provisions of the Tax Receivable Agreement. We recognized an additional liability in the amount of $1,094 for the TRA Payments due to the redeeming members, representing 85% of the aggregate tax benefits we expect to realize from the tax basis increases related to the redemption of LLC Interests, after concluding it was probable that such TRA Payments would be paid based on our estimates of future taxable income. During the thirteen weeks ended March 31, 2021 and March 25, 2020, payments of $0 and $6,569, inclusive of interest, were made to the parties to the Tax Receivable Agreement, respectively. As of March 31, 2021, the total amount of TRA Payments due under the Tax Receivable Agreement, was $234,048. See Note 13, Commitments and Contingencies, for more information relating to our liabilities under the Tax Receivable Agreement.

NOTE 11: EARNINGS (LOSS) PER SHARE

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 (loss) per share of Class B common stock under the two-class method has not been presented. However, shares of our Class B common stock outstanding for the period are considered potentially dilutive shares of Class A common stock under application of the if-converted method and are included in the computation of diluted earnings (loss) per share, except when the effect would be antidilutive.

The following table presents potentially dilutive securities, as of the end of the period, excluded from the computations of diluted earnings (loss) per share of Class A common stock for the thirteen weeks ended March 31, 2021 and March 25, 2020.

(1)    Number of securities outstanding at the end of the period that were excluded from the computation of diluted earnings (loss) per share of Class A common stock because the exercise price of the stock options exceeded the average market price of our Class A common stock during the period ("out-of-the-money").

(2)    Number of securities outstanding at the end of the period that were excluded from the computation of diluted earnings (loss) per share of Class A common stock because the performance conditions associated with these awards were not met assuming the end of the reporting period was the end of the performance period.

(3)    Number of securities outstanding at the end of the period that were excluded from the computation of diluted earnings (loss) per share of Class A common stock because the effect would have been anti-dilutive.

NOTE 13: COMMITMENTS AND CONTINGENCIES

Lease Commitments

We are obligated under various operating leases for Shacks and our home office space, expiring in various years through 2037. Under certain of these leases, we are liable for contingent rent based on a percentage of sales in excess of specified thresholds and are typically responsible for our proportionate share of real estate taxes, common area maintenance costs and other occupancy costs. See Note 7, Leases.

As security under the terms of one of our leases, we are obligated under a letter of credit totaling $130 as of March 31, 2021, which expires in February 2026. Additionally, in September 2017, we entered into a letter of credit in conjunction with our new home office lease in the amount of $603, which expires in August 2021 and renews automatically for one-year periods through January 31, 2034.

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.

Legal Contingencies

In March 2020, a claim was filed against Shake Shack alleging certain violations of the Fair Labor Standards Act. At a mediation between the parties, we agreed to settle the matter with the plaintiff and other employees who elect to participate in the settlement for $595. As of March 31, 2021, an accrual in the amount of $595 was recorded for this matter and related expenses.

In February 2018, a claim was filed against Shake Shack in California state court alleging certain violations of the California Labor Code. At a mediation between the parties, we agreed to settle the matter with the plaintiff and all other California employees who elect to participate in the settlement for $1,200. As of March 31, 2021, an accrual in the amount of $1,180 was recorded for this matter and related expenses.

Table of Contents

We are subject to various legal 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 March 31, 2021, the amount of the ultimate liability with respect to these matters was not material.

Liabilities under Tax Receivable Agreement

As described in Note 10, Income Taxes, we are a party to the Tax Receivable Agreement under which we are contractually committed to pay certain of the members of SSE Holdings 85% of the amount of any tax benefits that we actually realize, or in some cases are deemed to realize, as a result of certain transactions. We are not obligated to make any payments under the Tax Receivable Agreement until the tax benefits associated with the transactions that gave rise to the payments are realized. Amounts payable under the Tax Receivable Agreement are contingent upon, among other things, (i) generation of future taxable income over the term of the Tax Receivable Agreement and (ii) future changes in tax laws. If we do not generate sufficient taxable income in the aggregate over the term of the Tax Receivable Agreement to utilize the tax benefits, then we would not be required to make the related TRA Payments. During the thirteen weeks ended March 31, 2021 and March 25, 2020, we recognized liabilities totaling $1,094 and $310, respectively, relating to our obligations under the Tax Receivable Agreement, after concluding that it was probable that we would have sufficient future taxable income over the term of the Tax Receivable Agreement to utilize the related tax benefits. As of March 31, 2021 and December 30, 2020, our total obligations under the Tax Receivable Agreement were $234,048 and $232,954, respectively. There were no transactions subject to the Tax Receivable Agreement for which we did not recognize the related liability, as we concluded that we would have sufficient future taxable income to utilize all of the related tax benefits.

Recent Developments and Trends

We have experienced continued positive momentum in the business during the first quarter of 2021, and through April 28 ("fiscal April"), all while continuing to support our Shack teams, our guests and the communities in which we operate during the COVID-19 pandemic. With COVID cases stabilizing and more regions steadily loosening restrictions, we are optimistic that improving trends can continue for our industry. With a continued prioritization on health and safety, we have steadily re-opened dining rooms under modified operations to meet public health guidelines and evolving customer behaviors and expectations.

Same-Shack sales continued to improve across all regions, up 5.7% in the first quarter 2021, when compared to down 17.4% in the fourth quarter 2020, with performance driven by increases in in-Shack dining in both urban and suburban Shacks, combined with high levels of digital sales retention. Same-Shack sales in fiscal April were up 86% compared to the same period last year. As of the end of fiscal April 2021, the vast majority of Shacks were operating with open dining rooms, the majority of which continue to remain under varying levels of capacity restrictions, especially in urban Shacks. The Company continues to experience recovery across urban and suburban markets, however many major urban markets, such as Manhattan, remain materially below pre-COVID levels, while office, events and tourism traffic return.

Average weekly sales were $64,000 in the first quarter of 2021. Fiscal February was heavily impacted by severe winter weather, resulting in average weekly sales of $60,000, followed by a significant improvement to $68,000 in fiscal March, and continuing through fiscal April with $69,000. This continued improvement was driven by a substantial increase in in-Shack sales, as well as a high retention of digital sales.

During the first quarter of 2021, total digital sales, including orders placed on the Shake Shack app, website and third-party delivery platforms, represented 60% of Shack sales. Fiscal January and February digital mix was 64% and 62% of Shack sales, respectively, driven largely by increased delivery due to bad weather across large portions of the United States. Digital sales mix decreased to 54% of Shack sales in fiscal March and 51% of Shack sales in fiscal April, driven by an increase in in-Shack dining as the weather improved and parts of the country continued to re-open. Encouragingly, while in-Shack dining continues to increase, there continues to be a high level of digital sales retention with 90% of fiscal January's digital sales retained in fiscal April. Company-owned app and web channels continued to perform well in the first quarter 2021, with 2.4 million first-time purchasers between mid-March of 2020 and the end of fiscal March 2021, and over 230% year-over-year sales growth, when compared to the first quarter 2020.

Licensing revenue for the first quarter of 2021 was $4.6 million, reflecting a decrease of 9.9% versus the same period last year. We did, however, see improvement in total weekly sales performance throughout the quarter, with sales recovery led by improvements in both our international and domestic licensed Shacks, particularly in airports which are experiencing increases in Transportation Security Administration ("TSA") flight traffic.

Development Highlights

During the first quarter 2021, we opened ten new domestic Company-operated Shacks and two new international licensed Shacks. These openings were partially offset by the closure of one domestic Company-operated Shack and one international licensed Shack.

Though our rate of recovery and development plans continue to be impacted by the ongoing uncertainty due to COVID, we are aiming to open a total of between 35 and 40 new domestic Company-operated Shacks, and 15 to 20 new licensed Shacks, in fiscal 2021.

Liquidity Update

In March 2021, we issued $225 million aggregate principal amount of 0% Convertible Senior Notes due 2028 (the “Convertible Notes”) in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933. We granted an option to the initial purchasers to purchase up to an additional $25 million aggregate principal amount of Convertible Notes to cover over-allotments, which was subsequently fully exercised during March 2021, resulting in a total issuance of $250 million aggregate principal amount of Convertible Notes. The Convertible Notes will mature on March 1, 2028, unless earlier converted, redeemed or repurchased in certain circumstances. Upon conversion, we pay or deliver, as the case may be, cash, shares of Shake Shack’s Class A common stock or a combination of cash and shares of Shake Shack’s Class A common stock, at our election.

Shack Sales

Shack sales represent the aggregate sales of food, beverages and Shake Shack branded merchandise at our 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 performance at our Company-operated domestic Shacks that have been open for at least 24 months.

			Percentage change compared to prior year						9.1		%

Shack sales during the thirteen weeks ended March 31, 2021 increased 9.1% from the same prior-year period, primarily driven by the opening of 25 net new domestic Company-operated Shacks between March 25, 2020 and March 31, 2021, and to a lesser extent, an increase in same-Shack sales.

Same-Shack sales continued to improve across all regions, and increased 5.7% for the first quarter of 2021, compared to down 17.4% in the fourth quarter of 2020, with performance driven by increases in in-Shack dining in both urban and suburban Shacks, combined with high levels of digital sales retention. The increase in first quarter 2021 same-Shack sales was due to a price and sales mix increase of 18.0% — a combination of our end-of-year price increase in December, increased pricing on third-party delivery channels which rolled out over the early part of this fiscal year, and a higher number of items per check, particularly in our digital channels — partially offset by a 12.3% decrease in guest traffic. For the purpose of calculating same-Shack sales growth, Shack sales for 123 Shacks were included in the comparable Shack base as of the end of the first quarter of 2021 versus 90 Shacks for the first quarter of 2020.

Licensing Revenue

Licensing revenue is comprised of license fees, opening fees for certain licensed Shacks 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.

			Percentage of total revenue						3.0		%				3.6		%
			Dollar change compared to prior year						$	(508)
			Percentage change compared to prior year						(9.9)		%

Licensed revenue for the thirteen weeks ended March 31, 2021 decreased 9.9% to $4.6 million versus the same prior-year period, primarily due to reduced sales related to the COVID-19 pandemic, partially offset by a net increase of 9 Shacks opened between March 25, 2020 and March 31, 2021. As of the end of the first quarter 2021, 16 licensed Shacks remained temporarily closed due to COVID. Through the first quarter of 2021, we did, however, see improvement in total weekly sales performance throughout the quarter, with sales recovery led by improvements in both our international and domestic licensed Shacks, particularly in airports which are experiencing increases in TSA flight traffic.

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, change with sales volume, are impacted by menu mix and fluctuations in commodity costs, as well as geographic scale and proximity.

			Dollar change compared to prior year						$	5,066
			Percentage change compared to prior year						12.8		%

The increase in Food and paper costs for the thirteen weeks ended March 31, 2021 was primarily due to the opening of 25 net new domestic Company-operated Shacks between March 25, 2020 and March 31, 2021, as well as increased paper and packaging costs and beef costs.

Labor and Related Expenses

Labor and related expenses include domestic Company-operated Shack-level hourly and management wages, bonuses, payroll taxes, equity-based compensation, workers’ compensation expense and medical benefits. As we expect with other variable expense items, we expect labor costs to grow as our Shack sales grow. Factors that influence labor costs include minimum wage and payroll tax legislation, health care costs, size and location of the Shack and the performance of our domestic Company-operated Shacks.

			Dollar change compared to prior year						$	4,616
			Percentage change compared to prior year						11.1		%

The increase in Labor and related expenses for the thirteen weeks ended March 31, 2021 was primarily due to our annual wage rate increase, higher payroll taxes at the state level, and a more normalized level of performance related bonuses, including the impact of the opening of 25 net new domestic Company-operated Shacks between March 25, 2020 and March 31, 2021.

As a percentage of Shack sales, the increase in Labor and related expenses for the thirteen weeks ended March 31, 2021 was primarily due to our annual wage increase, a more normalized level of performance related bonuses and new Shack openings at higher levels of labor, partially offset by an increase in labor productivity at existing Shacks.

Other Operating Expenses

Other operating expenses consist of Shack-level repairs and maintenance, utilities and other operating expenses incidental to operating our domestic Company-operated Shacks, such as delivery commissions, credit card fees, non-perishable supplies, and business insurance.

The increase in Occupancy and related expenses for the thirteen weeks ended March 31, 2021 was primarily due to the opening of 25 net new domestic Company-operated Shacks between March 25, 2020 and March 31, 2021.

As a percentage of Shack sales, Occupancy and related expenses for the thirteen weeks ended March 31, 2021 was relatively consistent with the same-prior year period, and continues to be impacted by sales deleverage, particularly in our high-volume urban Shacks.

General and Administrative Expenses

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

			Dollar change compared to prior year						$	3,374
			Percentage change compared to prior year						20.8		%

The increase in General and administrative expenses for the thirteen weeks ended March 31, 2021 was primarily due to continued investment across the business, including an increase in headcount to support the strategic growth plan, and increased investments in marketing and our digital initiatives.

As a percentage of total revenue, the increase in General and administrative expenses for the thirteen weeks ended March 31, 2021 was primarily due primarily to drivers described above.

Depreciation and Amortization Expense

Depreciation and amortization expense primarily consists of the depreciation of fixed assets, including leasehold improvements and equipment, as well as financing equipment lease assets.

			Dollar change compared to prior year						$	1,958
			Percentage change compared to prior year						16.6		%

The increase in Depreciation and amortization expense for the thirteen weeks ended March 31, 2021 was primarily due to incremental depreciation of capital expenditures related to the opening of 25 net new domestic Company-operated Shacks between March 25, 2020 and March 31, 2021 and increased technology investments to support our digital initiatives.

As a percentage of total revenue, the increase in Depreciation and amortization expense for the thirteen weeks ended March 31, 2021 was primarily due to the aforementioned items.

Pre-Opening Costs

Pre-opening costs consist primarily 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 may initially experience higher pre-opening costs than our established geographic market areas, such as the New York City metropolitan area, where we have greater economies of scale and incur lower travel and lodging costs for our training team.

The increase in Pre-opening costs for the thirteen weeks ended March 31, 2021 was due to the increased fiscal 2021 development pipeline for new domestic Company-operated Shacks, including those expected to open in the first half of the fiscal year.

Impairment and Loss on Disposal of Assets

Impairment and loss on disposal of assets include impairment charges related to our long-lived assets, which includes property and equipment, as well as operating and finance lease assets. Additionally, Impairment and loss on disposal of assets includes the net book value of assets that have been retired and consists primarily of furniture, equipment and fixtures that were replaced in the normal course of business.

The decrease in Impairment and loss on disposal of assets for the thirteen weeks ended March 31, 2021 was primarily due to asset impairment charges of $1.1 million in the first quarter of 2020 related to the impairment of one Shack. In addition, loss on disposal of assets decreased due to several Shack renovations in fiscal 2020.

Other Income (Expense), Net

Other income (expense), net consists of adjustments to liabilities under our Tax Receivable Agreement, dividend income, interest income and net unrealized and realized gains and losses from the sale of marketable securities.

The increase in Other income (expense), net for the thirteen weeks ended March 31, 2021 was primarily due to a decline in unrealized losses related to our investments in marketable securities, partially offset by a decrease in dividend income.

Interest Expense

Interest expense primarily consists of interest and fees on our Revolving Credit Facility, imputed interest related to our financing equipment leases, amortization of deferred financing costs, and interest on the current portion of our liabilities under the Tax Receivable Agreement.

Income Tax Expense (Benefit)

We are the sole managing member of SSE Holdings, and as a result, consolidate the financial results of SSE Holdings. SSE Holdings 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, as well as any stand-alone income or loss generated by Shake Shack Inc. We are also subject to withholding taxes in foreign jurisdictions.

Our effective income tax rates for the thirteen weeks ended March 31, 2021 and March 25, 2020 were 105.5% and (8.8)%, respectively. The increase was primarily driven by lower pre-tax book income resulting in a loss, causing tax credits and windfall tax benefits related to equity-based compensation to have an increasing effect on the tax rate, as well as a reduction of a valuation allowance. Additionally, an increase in our ownership interest in SSE Holdings increases our share of the taxable income (loss) of SSE Holdings. Our weighted-average ownership interest in SSE Holdings was 93.0% and 91.6% for the thirteen weeks ended March 31, 2021 and March 25, 2020, respectively.

Net Loss Attributable to Non-Controlling Interests

We are the sole managing member of SSE Holdings and have the sole voting power in, and control the management of, SSE Holdings. Accordingly, we consolidate the financial results of SSE Holdings and report a non-controlling interest on our Condensed Consolidated Statements of Income (Loss), representing the portion of Net income (loss) attributable to the other members of SSE Holdings. The Third Amended and Restated Limited Liability Company Agreement of SSE Holdings 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. In connection with any redemption or exchange, we will receive a corresponding number of LLC Interests, increasing our total ownership interest in SSE Holdings. The weighted average ownership percentages for the applicable reporting periods are used to attribute net income (loss) and other comprehensive income to Shake Shack Inc. and the non-controlling interest holders.

The increase in Net loss attributable to non-controlling interests for the thirteen weeks ended March 31, 2021 was primarily due to an increase in net loss for SSE Holdings for the period, partially offset by a decrease in the non-controlling interest holders' weighted average ownership, which was 7.0% and 8.4% for the thirteen weeks ended March 31, 2021 and March 25, 2020, respectively.

NON-GAAP FINANCIAL MEASURES

To supplement the condensed consolidated financial statements, which are prepared and presented in accordance with U.S. GAAP, we use the following non-GAAP financial measures: Shack-level operating profit, Shack-level operating profit margin, EBITDA, adjusted EBITDA, adjusted EBITDA margin, adjusted pro forma net income and adjusted pro forma earnings per fully exchanged and diluted share (collectively the "non-GAAP financial measures").

Shack-Level Operating Profit

Shack-level operating profit is defined as Shack sales less Shack-level operating expenses including Food and paper costs, Labor and related expenses, Other operating expenses and Occupancy and related expenses.

How This Measure Is Useful

When used in conjunction with GAAP financial measures, Shack-level operating profit and Shack-level operating profit margin are supplemental measures of operating performance that the Company believes are useful measures to evaluate the performance and profitability of its Shacks. Additionally, Shack-level operating profit and Shack-level operating profit margin are key metrics used internally by management to develop internal budgets and forecasts, as well as assess the performance of its Shacks relative to budget and against prior periods. It is also used to evaluate employee compensation as it serves as a metric in certain performance-based employee bonus arrangements. The Company believes presentation of Shack-level operating profit and Shack-level operating profit margin provides investors with a supplemental view of its operating performance that can provide meaningful insights to the underlying operating performance of the Shacks, as these measures depict the operating results that are directly impacted by the Shacks and exclude items that may not be indicative of, or are unrelated to, the ongoing operations of the Shacks. It may also assist investors to evaluate the Company's performance relative to peers of various sizes and maturities and provides greater transparency with respect to how management evaluates the business, as well as the financial and operational decision-making.

Limitations of the Usefulness of this Measure

Shack-level operating profit and Shack-level operating profit margin may differ from similarly titled measures used by other companies due to different methods of calculation. Presentation of Shack-level operating profit and Shack-level operating profit margin is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP. Shack-level operating profit excludes certain costs, such as General and administrative expenses and Pre-opening costs, which are considered normal, recurring cash operating expenses and are essential to support the operation and development of the Company's Shacks. Therefore, this measure may not provide a complete understanding of the Company's operating results as a whole and Shack-level operating profit and Shack-level operating profit margin should be reviewed in conjunction with the Company's GAAP financial results. A reconciliation of Shack-level operating profit to Operating loss, the most directly comparable GAAP financial measure, is set forth below.

EBITDA and Adjusted EBITDA

EBITDA is defined as Net income (loss) before interest expense (net of interest income), Income tax expense (benefit) and Depreciation and amortization expense. Adjusted EBITDA is defined as EBITDA (as defined above) excluding equity-based compensation expense, deferred lease cost, Impairment and loss on the disposal of assets, amortization of cloud-based software implementation costs, as well as certain non-recurring items that the Company does not believe directly reflect its core operations and may not be indicative of the Company's recurring business operations.

How These Measures Are Useful

When used in conjunction with GAAP financial measures, EBITDA and adjusted EBITDA are supplemental measures of operating performance that the Company believes are useful measures to facilitate comparisons to historical performance and competitors' operating results. Adjusted EBITDA is a key metric used internally by management to develop internal budgets and forecasts and also serves as a metric in its performance-based equity incentive programs and certain bonus arrangements. The Company believes presentation of EBITDA and adjusted EBITDA provides investors with a supplemental view of the Company's operating performance that facilitates analysis and comparisons of its ongoing business operations because they exclude items that may not be indicative of the Company's ongoing operating performance.

Limitations of the Usefulness of These Measures

EBITDA and adjusted EBITDA may differ from similarly titled measures used by other companies due to different methods of calculation. Presentation of EBITDA and adjusted EBITDA is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP. EBITDA and adjusted EBITDA exclude certain normal recurring expenses. Therefore, these measures may not provide a complete understanding of the Company's performance and should be reviewed in conjunction with the GAAP financial measures. A reconciliation of EBITDA and adjusted EBITDA to Net income (loss), the most directly comparable GAAP measure, is as follows.

Adjusted Pro Forma Net Income and Adjusted Pro Forma Earnings Per Fully Exchanged and Diluted Share

Adjusted pro forma net income represents net income (loss) attributable to Shake Shack Inc. assuming the full exchange of all outstanding SSE Holdings, LLC membership interests ("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 and may not be indicative of our recurring business operations. Adjusted pro forma earnings per fully exchanged and diluted share is calculated by dividing adjusted pro forma net income (loss) by the weighted-average shares of Class A common stock outstanding, assuming the full exchange of all outstanding LLC Interests, after giving effect to any dilutive securities such as outstanding equity-based awards.

How These Measures Are Useful

When used in conjunction with GAAP financial measures, adjusted pro forma net income and adjusted pro forma earnings per fully exchanged and diluted share are supplemental measures of operating performance that we believe are useful measures to evaluate our performance period over period and relative to our competitors. By assuming the full exchange of all outstanding LLC Interests, we believe these measures facilitate comparisons with other companies that have different organizational and tax structures, as well as comparisons period over period because it eliminates the effect of any changes in net income (loss) attributable to Shake Shack Inc. driven by increases in our ownership of SSE Holdings, which are unrelated to our operating performance, and excludes items that are non-recurring or may not be indicative of our ongoing operating performance.

Limitations of the Usefulness of These Measures

Adjusted pro forma net income and adjusted pro forma earnings per fully exchanged and diluted share are not necessarily comparable to similarly titled measures used by other companies due to different methods of calculation. Presentation of adjusted pro forma net income and adjusted pro forma earnings per fully exchanged and diluted share should not be considered alternatives to net income (loss) and earnings (loss) per share, as determined under GAAP. While these measures are useful in evaluating our performance, it does not account for the earnings attributable to the non-controlling interest holders and therefore does not provide a complete understanding of the net income (loss) attributable to Shake Shack Inc. Adjusted pro forma net income and adjusted pro forma earnings per fully exchanged and diluted share should be evaluated in conjunction with our GAAP financial results. 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.

Our primary sources of liquidity are cash from operations, cash and cash equivalents on hand, short-term investments and availability under our Revolving Credit Facility. In March 2021, we issued 0% Convertible Notes of Convertible Debt, and received $243.8 million of proceeds, net of discounts. Refer to Note 6, Debt, for further discussion.

As of March 31, 2021, we maintained a cash and cash equivalents balance of $375.0 million and a short-term investments balance of $40.9 million within Marketable securities.

On June 8, 2018, we filed a Registration Statement on Form S-3 with the SEC which permits us to issue a combination of securities described in the prospectus in one or more offerings from time to time. To date, we have not experienced difficulty accessing the capital markets; however, future volatility in the capital markets may affect our ability to access those markets or increase the costs associated with issuing debt or equity instruments.

Our primary requirements for liquidity are to fund our working capital needs, operating and finance lease obligations, capital expenditures and general corporate needs. Our requirements for working capital are generally 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 and digital infrastructure.

In addition, we are obligated to make payments to certain members of SSE Holdings under the Tax Receivable Agreement. As of March 31, 2021, such obligations totaled $234.0 million. Amounts payable under the Tax Receivable Agreement are contingent upon, among other things, (i) generation of future taxable income over the term of the Tax Receivable Agreement and (ii) future changes in tax laws. If we do not generate sufficient taxable income in the aggregate over the term of the Tax Receivable Agreement to utilize the tax benefits, then we would not be required to make the related TRA Payments. 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 flow 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.

In response to the uncertain market conditions resulting from the onset of the COVID-19 pandemic, we took the following actions in fiscal 2020.

•On April 17, 2020, we announced an "at-the-market" equity offering program (the "ATM Program"), under which we may offer and sell shares of our Class A common stock having an aggregate price of up to $75.0 million from time to time. On April 21, 2020, we completed the sale of 233,467 shares of our Class A common stock pursuant to the ATM Program and received $9.8 million of proceeds, net of commissions. The proceeds were used to purchase newly-issued LLC Interests.

•On April 21, 2020, we completed an underwritten offering of 3,416,070 shares of our Class A common stock, resulting in $135.9 million of proceeds, net of underwriting discounts and commissions. The proceeds were used to purchase newly-issued LLC Interests.

•In May 2020, we entered into an amendment to our Revolving Credit Facility that provided for a number of enhanced modifications to reflect the current and ongoing impact from COVID-19. Our Revolving Credit Facility was further amended in March 2021, resulting in a modification of the applicable covenants and restrictions in the Credit Agreement to permit the incurrence of the Convertible Notes, including obligations and transactions in connection therewith. Refer to Note 6, Debt, for further information.

•In March 2020, we drew down the full $50.0 million available under the Revolving Credit Facility to enhance liquidity and financial flexibility given the uncertain market conditions created by the COVID-19 pandemic. We repaid this amount in full, plus interest, in June 2020. As of March 31, 2021, we were in compliance with all covenants.

We believe our existing cash and marketable securities balances will be sufficient to fund our operating and finance 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.

			Thirteen Weeks Ended
(in thousands)			March 31 2021						March 25 2020
Net cash provided by operating activities			$	9,951					$	7,484
Net cash provided by (used in) investing activities			(27,228)						649
Net cash provided by financing activities			245,403						42,574
Increase in cash and cash equivalents			228,126						50,707
Cash and cash equivalents at beginning of period			146,873						37,099
Cash and cash equivalents at end of period			$	374,999					$	87,806

Operating Activities

For the thirteen weeks ended March 31, 2021 net cash provided by operating activities was $10.0 million compared to $7.5 million for the thirteen weeks ended March 25, 2020, an increase of $2.5 million. The increase was primarily due to change in operating assets and liabilities of $3.9 million and an increase in net income of $1.7 million, partially offset by the impact of non-cash charges of $3.1 million.

The $3.9 million change in our operating asset and liability balances was primarily driven by Accrued wages and related liabilities being a source of cash of $2.9 million in the first quarter of 2021, primarily driven by higher accruals associated with payroll costs, compared to a use of cash of $5.1 million in the first quarter of 2020; Accounts payable being a source of cash of $1.5 million in the first quarter of 2021, driven by timing of payments, compared to a use of cash of $4.4 million in the first quarter of 2020; partially offset by Accrued expenses being a use of cash of $9.4 million in the first quarter of 2021, due to the timing of accruals associated with tax payments, compared to a use of cash of $6.3 million in the first quarter of 2020; Other long-term liabilities being a use of cash of $1.8 million in the first quarter of 2021, due to the timing of tax payments, compared to a source of cash of $0.5 million in the first quarter of 2020; and Accounts Receivable being a source of cash of $0.6 million in the first quarter of 2021, primarily driven by timing of cash receipts of open receivables, compared to a source of cash of $3.2 million in the first quarter of 2020.

Investing Activities

For the thirteen weeks ended March 31, 2021 net cash used in investing activities was $27.2 million compared to net cash provided by investing activities of $0.6 million for the thirteen weeks ended March 25, 2020, a decrease of $27.8 million. This decrease was primarily due to a decrease of $20.0 million of proceeds from sales of marketable securities, an increase of $4.0 million in capital expenditures to support our real estate development and digital initiatives and increased purchases of marketable securities of $3.9 million.

Financing Activities

For the thirteen weeks ended March 31, 2021 net cash provided by financing activities was $245.4 million compared to $42.6 million for the thirteen weeks ended March 25, 2020, an increase of $202.8 million. This increase was primarily due to $243.8 million in net cash proceeds from the issuance of the Convertible Notes, decreased payments made under the Tax Receivable Agreement, and increased proceeds from stock option exercises, partially offset by $50.0 million in gross cash proceeds from the drawdown of funds from our Revolving Credit Facility in the first quarter of 2020 — which was repaid in full, plus interest, in the second quarter of 2020.

Revolving Credit Facility

In August 2019, we entered into a Revolving Credit Facility, which permits borrowings up to $50.0 million, of which the entire amount is available immediately, with the ability to increase available borrowings up to an additional $100.0 million, to be made available subject to satisfaction of certain conditions. The Revolving Credit Facility also permits the issuance of letters of credit upon our request of up to $15.0 million.

In March 2020, we drew down the full $50.0 million available under the Revolving Credit Facility to enhance liquidity and financial flexibility given the uncertain market conditions created by the COVID-19 pandemic. We repaid this amount in full, plus interest, in June 2020.

In May 2020, we entered into a First Amendment, which, among other things, provided for modified financial covenant compliance requirements for a period of time. The First Amendment required us to maintain minimum liquidity of $25.0 million through July 1, 2021 and outstanding borrowings during the applicable period covered by the First Amendment bore interest at either: (i) LIBOR plus a percentage ranging from 1.0% to 2.5% or (ii) the base rate plus a percentage ranging from 0.0% to 1.5%, in each case depending on our net lease adjusted leverage ratio.

In March 2021, we entered into a Second Amendment. The Second Amendment modified the applicable covenants and restrictions in the Credit Agreement to permit the incurrence of the Convertible Notes (as defined below), including obligations and transactions in connection therewith. In addition, the Second Amendment, among other things, (i) extended the period applicable to the increased interest rate margin as set forth in the First Amendment; (ii) shortened the maturity date of the Revolving Credit Facility from August 2024 to September 2022 and (iii) added mechanics relating to the transition from the use of LIBOR to SOFR upon the discontinuance or unavailability of LIBOR.

Subsequently, and also in March 2021, we entered into a Third Amendment with JPMorgan Chase Bank, N.A. (as successor agent to Wells Fargo Bank, National Association), as administrative agent, and the lenders party thereto. In addition, in March 2021, Wells Fargo Bank resigned as administrative agent under the Revolving Credit Facility and assigned its commitments thereunder to JPMorgan Bank, N.A. The Third Amendment appoints JPMorgan Bank, N.A. as administrative agent under the Revolving Credit Facility. In addition, the Third Amendment, among other things, extends the maturity date of the Revolving Credit Facility from September 2022 to March 2026. As of March 31, 2021 and December 30, 2020, no amounts were outstanding under the Revolving Credit Facility.

The obligations under the Revolving Credit Facility are 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' direct and indirect subsidiaries (with certain exceptions).

The Revolving Credit Facility requires us to comply with maximum net lease adjusted leverage and minimum fixed charge coverage ratios. We are not subject to these coverage ratios for a period of time due to the Second Amendment to the Revolving Credit Facility described above. In addition, the Revolving Credit Facility contains other customary affirmative and negative covenants, including those which (subject to certain exceptions and dollar thresholds) limit our ability to incur debt; incur liens; make investments; engage in mergers, consolidations, liquidations or acquisitions; dispose of assets; make distributions on or repurchase equity securities; engage in transactions with affiliates; and prohibits us, with certain exceptions, from engaging in any line of business not related to our current line of business. As of March 31, 2021, we were in compliance with all covenants.

As of March 31, 2021, the Revolving Credit Facility had unamortized deferred financing costs of $0.1 million, and was included in Other assets on the Condensed Consolidated Balance Sheet. Total interest expense related to the Revolving Credit Facility were $0.4 million and $0.1 million for the thirteen weeks ended March 31, 2021 and March 25, 2020, respectively. Total interest expense for the thirteen weeks ended March 31, 2021 primarily included write-off of previously capitalized costs on the Revolving Credit Facility.

Convertible Notes

In March 2021, we issued $225.0 million aggregate principal amount of 0% Convertible Senior Notes due 2028 in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933. We granted an option to the initial purchasers to purchase up to an additional $25.0 million aggregate principal amount of Convertible Notes to cover over-allotments, which was subsequently fully exercised during March 2021, resulting in a total issuance of $250.0 million aggregate principal amount of Convertible Notes. The Convertible Notes will mature on March 1, 2028, unless earlier converted, redeemed or repurchased in certain circumstances. Upon conversion, we pay or deliver, as the case may be, cash, shares of Shake Shack’s Class A common stock or a combination of cash and shares of Shake Shack’s Class A common stock, at our election.

The Convertible Notes are convertible at the option of the holders at any time prior to the close of business on the business day immediately preceding December 1, 2027, only under the following circumstances: (1) during any fiscal quarter commencing after the fiscal quarter ending on June 30, 2021 (and only during such fiscal quarter), if the last reported sale price of our Class A common stock, par value $0.001 per share, for at least 20 trading days (whether or not consecutive) during a period of 30

consecutive trading days ending on, and including, the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price for the Convertible Notes on each applicable trading day; (2) during the five business day period after any ten consecutive trading day period in which the trading price (as defined in the Indenture) per $1,000 principal amount of the Convertible Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of Class A common stock and the conversion rate for the Convertible Notes on each such trading day; (3) if we call such Convertible Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date, but only with respect to the Convertible Notes called (or deemed called) for redemption; and (4) upon the occurrence of specified corporate events as set forth in the Indenture. On or after December 1, 2027, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders of the Convertible Notes may convert all or any portion of their Convertible Notes at any time, regardless of the foregoing circumstances.

The Convertible Notes had an initial conversion rate of 5.8679 shares of Shake Shack’s Class A common stock per $1,000 principal amount of Convertible Notes, which is equivalent to an initial conversion price of approximately $170.42 per share of Shake Shack’s Class A common stock.

We may not redeem the Convertible Notes prior to March 6, 2025. We may redeem for cash all or any portion of the Convertible Notes, at our option, on or after March 6, 2025 if the last reported sale price of Shake Shack’s Class A common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption at a redemption price equal to 100% of the principal amount of the Convertible Notes to be redeemed, plus accrued and unpaid special interest, if any, to, but excluding, the redemption date.

In addition, if we undergo a fundamental change (as defined in the indenture governing the Convertible Notes), subject to certain conditions, holders may require us to repurchase for cash all or any portion of their Convertible Notes at a repurchase price equal to 100% of the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid special interest, if any, to, but excluding, the fundamental change repurchase date. In addition, following certain corporate events that occur prior to the maturity date of the Convertible Notes or if we deliver a notice of redemption in respect of some or all of the Convertible Notes, we will, in certain circumstances, increase the conversion rate of the Convertible Notes for a holder who elects to convert our Convertible Notes in connection with such a corporate event or convert our Convertible Notes called (or deemed called) for redemption during the related redemption period, as the case may be.

Contemporaneously with the issuance of the Convertible Notes, Shake Shack Inc. entered into an Intercompany Note with SSE Holdings, LLC. SSE Holdings promises to pay Shake Shack, Inc., for value received, the principal amount with interest of the Intercompany Note in March 2028. Shake Shack Inc. will exercise its right to convert the Intercompany Note to maintain at all times a one-to-one ratio between the number of common units, directly or indirectly, by Shake Shack Inc and the aggregate number of outstanding shares of common stock.

As of March 31, 2021, the Convertible Notes had a gross principal balance of $250.0 million and a balance of $242.9 million, net of unamortized discount and debt issuance costs of $7.1 million. As of March 31, 2021, the unamortized balance of discount and debt issuance costs was recorded as a contra-liability and netted with Long-term debt on the Condensed Consolidated Balance Sheets and was being amortized as interest expense using the effective interest method. Total amortization expense was $0.1 million for the thirteen weeks ended March 31, 2021 and was included in Interest expense in the Condensed Consolidated Statements of Income (Loss). In connection with the Convertible Notes, we also incurred costs of $0.2 million, including consulting and advisory fees, in the thirteen weeks ended March 31, 2021 and was included in General and administrative expense in the Condensed Consolidated Statements of Income (Loss).

At March 31, 2021, the fair value of the Convertible Notes was approximately $248.1 million, based on external pricing data, including available quoted market prices of these instruments, and consideration of comparable debt instruments with similar interest rates and trading frequency, among other factors, and is classified as a Level 2 measurement within the fair value hierarchy.
