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 ("PSLRA"), which are subject to known and unknown risks, uncertainties and other important factors that may cause actual results to be materially different from the statements made herein. All statements other than statements of historical fact included in this Form 10-Q are forward-looking statements, including, but not limited to, statements about the Company's growth, strategic plan, and liquidity. Forward-looking statements discuss the Company's current expectations and projections relating to its 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," "future," "intend," "likely," "outlook," "potential," "project," "projection," "plan," "seek," "may," "could," "would," "will," "should," "can," "can have," the negatives thereof and other similar expressions.

All forward-looking statements are expressly qualified in their entirety by these cautionary statements. Some of the factors which could cause results to differ materially from the Company's expectations include the Company's ability to develop and open new Shacks on a timely basis, increased costs or shortages or interruptions in the supply and delivery of products, increased labor costs or shortages, inflationary pressures, the Company's management of its digital capabilities and expansion into delivery, as well as kiosk, drive-thru and multiple format investments, the Company's ability to maintain and grow sales at existing Shacks, and risks relating to the restaurant industry generally, and the impact of any material weakness in the Company's internal controls over financial reporting identified in connection with the restatement described in the Company's Annual Report on Form 10-K filed with the Securities and Exchange Commission on February 29, 2024 or otherwise. You should evaluate all forward-looking statements made in this Form 10-Q in the context of the risks and uncertainties disclosed in the Company's Annual Report on Form 10-K for the fiscal year ended December 27, 2023 as filed with the Securities and Exchange Commission (the "SEC").

The forward-looking statements included in this Form 10-Q are made only as of the date hereof. The Company undertakes 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.

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"). Shake Shack Inc. is the sole managing member of SSE Holdings and, as sole managing member, the Company operates and controls all of the business and affairs of SSE Holdings. As a result, the Company consolidates the financial results of SSE Holdings and reports a non-controlling interest representing the economic interest in SSE Holdings held by the other members of SSE Holdings. As of March 27, 2024 the Company owned 93.4% 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.

The Company operates and licenses Shake Shack restaurants ("Shacks"), which serve burgers, chicken, hot dogs, crinkle cut fries, shakes, frozen custard, beer, wine and more. As of March 27, 2024, there were 525 Shacks in operation system-wide, of which 299 were Company-operated Shacks and 226 were licensed Shacks.

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 its Annual Report on Form 10-K for the fiscal year ended December 27, 2023 ("2023 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 the rules and regulations of the Securities and Exchange Commission. These interim Condensed Consolidated Financial Statements should be read in conjunction with the consolidated financial statements and related notes thereto included in its 2023 Form 10-K. In the Company's opinion, all adjustments, which are normal and recurring in nature, necessary for a fair presentation of the 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 the Company has the majority economic interest in SSE Holdings and, as the sole managing member, has 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, the Company consolidates SSE Holdings. The assets and liabilities of SSE Holdings represent substantially all of the Company's consolidated assets and liabilities with the exception of certain deferred taxes and liabilities under the Tax Receivable Agreement. As of March 27, 2024 and December 27, 2023, the net assets of SSE Holdings were $394,523 and $388,250, respectively. The assets of SSE Holdings are subject to certain restrictions in SSE Holdings' revolving credit agreement.

Fiscal Year

The Company operates on a 52/53 week fiscal year ending on the last Wednesday of December. Fiscal 2024 contains 52 weeks and ends on December 25, 2024. Fiscal 2023 contained 52 weeks and ended on December 27, 2023. 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 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.

Shake Shack Inc. Form 10-Q | 9

Recently Issued Accounting Pronouncements

The Company reviewed all recently issued accounting pronouncements and concluded that they were not applicable or not expected to have a significant impact on its Condensed Consolidated Financial Statements.

NOTE 3: REVENUE

Revenue Recognition

Revenue primarily 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 the Company expects to be entitled to in exchange for those goods or services.

Shack Sales

Revenue from Shack sales is recognized when payment is tendered at the point of sale, net of discounts as the performance obligation has been satisfied at that time. Sales tax collected from guests is excluded from Shack sales and the obligation is included as sales tax payable until the taxes are remitted to the appropriate taxing authorities.

Delivery services are fulfilled by third-party delivery partners whether ordered through the Shack app, website ("Company-owned platforms") or through third-party delivery platforms. Revenue from orders through Company-owned platforms includes delivery fees and is recognized when the delivery partner transfers the order to the guest as the Company controls the delivery. For these sales, the Company receives payment directly from the guest at the time of sale. Revenue from orders through third-party delivery platforms is recognized when the order is transferred to the third-party delivery partner and excludes delivery fees collected by the delivery partner as the Company does not control the delivery. The Company receives payment from the delivery partner subsequent to the transfer of the order and the payment terms are short-term in nature. For all delivery sales, the Company is considered the principal and recognizes revenue on a gross basis.

The Company sells gift cards which do not have expiration dates. Revenue from gift cards is recognized when gift cards are redeemed by the customer or, in the event a gift card is not expected to be redeemed, in proportion to actual redemptions of gift cards ("gift card breakage"). The gift card breakage rate is determined from historical gift card redemption patterns. Gift card breakage income for the thirteen weeks ended March 27, 2024 and March 29, 2023 was $134 and $106, respectively. Gift card breakage income is included in Shack sales in the Condensed Consolidated Statements of Income (Loss).

Licensing Revenue

Licensing revenue includes 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 good or service transferred to the licensee 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 license and considered one performance obligation per Shack.

The Company determines the transaction price for each contract, which is comprised of the initial territory fee and an estimate of the total Shack opening fees the Company expects to be entitled to. The calculation of total Shack opening fees requires judgment, as it is based on an estimated number of Shacks the Company expects the licensee to open. The transaction price is then allocated equally to each Shack expected to open. The performance obligation is satisfied over time, starting when a Shack opens through the end of the license term for the related Shack, therefore 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 license agreement and payment for the Shack opening fees is received either in advance of or upon opening the related Shack. These payments are initially deferred and

10 | Shake Shack Inc. Form 10-Q

recognized in revenue as the performance obligations are satisfied. Revenue from sales-based royalties is recognized as the related sales occur.

Revenue disaggregated by type was as follows:

	Thirteen Weeks Ended
	March 27 2024		March 29 2023
Shack sales	$	280,552	$	244,254
Licensing revenue:
Sales-based royalties	9,633		8,778
Initial territory and opening fees	319		246
Total revenue	$	290,504	$	253,278

The aggregate amount of the transaction price allocated to performance obligations that were unsatisfied or partially unsatisfied as of March 27, 2024 was $23,370. The Company expects 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

Contract liabilities and receivables from contracts with customers were as follows:

	March 27 2024		December 27 2023
Shack sales receivables	$	9,012	$	9,884
Licensing receivables, net of allowance for doubtful accounts	3,880		4,610
Gift card liability	2,325		2,603
Deferred revenue, current	1,261		1,192
Deferred revenue, long-term	16,919		17,157

Revenue recognized that was included in the respective liability balances at the beginning of the period was as follows:

NOTE 6: DEBT

Convertible Notes

The Company's $250,000 aggregate principal amount of 0% Convertible Senior Notes due 2028 (“Convertible Notes”) will mature on March 1, 2028, unless earlier converted, redeemed or repurchased in certain circumstances. Upon conversion, the Company pays or delivers, as the case may be, cash, shares of Class A common stock or a combination of cash and shares of Class A common stock, at the Company's 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 the Company's 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 one thousand dollar 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 the Company calls 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 Class A common stock per one thousand dollar principal amount of Convertible Notes, which is equivalent to an initial conversion price of approximately $170.42 per share of Class A common stock. The fair value of the Convertible Notes was approximately $226,795 and $205,000, respectively, as of March 27, 2024 and December 27, 2023, 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.

Revolving Credit Facility

The Company maintains a revolving credit facility agreement ("Revolving Credit Facility") which permits borrowings up to $50,000 with the ability to increase available borrowings up to an additional $100,000, subject to satisfaction of certain conditions. The Revolving Credit Facility has a maturity date of March 5, 2026.

In June 2023, the Company entered into the fourth amendment to the Revolving Credit Facility ("Fourth Amendment"), which, among other things, modified the benchmark interest rate to either: (i) the base rate plus applicable margin ranging from 0.0% to 1.5% or (ii) the Secured Overnight Financing Rate (“SOFR”) plus applicable margin ranging from 1.0% to 2.5%, in each case

Shake Shack Inc. Form 10-Q | 13

dependent upon the net lease adjusted leverage ratio. As of March 27, 2024 and December 27, 2023, 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 the Company to comply with maximum net lease adjusted leverage and minimum fixed charge coverage ratios, as well as other customary affirmative and negative covenants. As of March 27, 2024, the Company was in compliance with all covenants.

The Revolving Credit Facility also permits the issuance of letters of credit upon our request of up to $15,000. As of March 27, 2024 and December 27, 2023, the Company had outstanding letters of credit of $3,310 and $3,147, respectively, in connection with the Revolving Credit Facility.

NOTE 7: LEASES

Nature of Leases

Shake Shack currently leases all of its Company-operated Shacks, the home office and certain equipment under various non-cancelable lease agreements that expire on various dates through 2045. The Company evaluates 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. The Company evaluates whether it controls the use of the asset, which is determined by assessing whether substantially all economic benefit from the use of the asset is obtained, and whether the Company has the right to direct the use of the asset. If these criteria are met, the Company has identified a lease within the contract, and therefore a right of use asset and lease liability are recorded on the Condensed Consolidated Balance Sheet. Upon possession of a leased asset, the Company determines whether the lease is an operating or finance lease. All of the Company's real estate leases are classified as operating leases and most equipment leases are classified as finance leases.

Generally, 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 the Company would exercise the renewal options. Real estate leases typically contain fixed minimum rent payments and/or contingent rent payments which are 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.

For operating leases, fixed lease payments are recognized as operating lease costs on a straight-line basis over the lease term within the Condensed Consolidated Statements of Income (Loss) in the following line items. Lease expense incurred before a Shack opens is recorded in Pre-opening costs. Once a Company-operated Shack opens, the straight-line lease expense and contingent rent, if applicable, are recorded in Occupancy and related expenses. Many of these leases also require the Company to pay real estate taxes, common area maintenance costs and other occupancy costs which are included in Occupancy and related expenses. Finance leases are recognized in depreciation expense on a straight-line basis over the remaining lease term, along with recognition of interest expense associated with accretion of the lease liability.

14 | Shake Shack Inc. Form 10-Q

For both operating and finance leases that contain lease and non-lease components, the components are combined and accounted for as a single lease component. Variable lease costs for both operating and finance leases, if any, are recognized as incurred. Leases with a term of 12 months or less are deemed short-term and are not recognized on the Condensed Consolidated Balance Sheets. Fixed lease payments for short-term leases are recognized on a straight-line basis over the lease term.

The Company calculates operating lease assets and lease liabilities as the present value of fixed lease payments over the reasonably certain lease term beginning at the commencement date. The Company uses its incremental borrowing rate ("IBR") in determining the present value of future lease payments as there are no explicit rates provided in the leases. The IBR 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 IBR is the Company's credit rating and is subject to judgment. The credit rating used to develop the IBR is determined by utilizing the credit ratings of other public companies with similar financial information as SSE Holdings.

The Company expends cash for leasehold improvements to build out and equip leased properties. Generally, a portion of the leasehold improvements and building costs are reimbursed by the landlords through landlord incentives pursuant to agreed-upon terms in the lease agreements. Landlord incentives usually take the form of cash, full or partial credits against future minimum or contingent rents otherwise payable by the Company, or a combination thereof. In most cases, landlord incentives are received after the Company takes possession of the property and as milestones are met during the construction of the property. The Company includes these amounts in the measurement of the initial operating lease liability, and lease asset.

NOTE 8: NON-CONTROLLING INTERESTS

Shake Shack is the primary beneficiary and sole managing member of SSE Holdings and, as a result, consolidates the financial results of SSE Holdings. The Company reports 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

16 | Shake Shack Inc. Form 10-Q

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, the Company will receive a corresponding number of LLC Interests, increasing the total ownership interest in SSE Holdings. Changes in the ownership interest in SSE Holdings while the Company retains its 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:

	March 27, 2024			December 27, 2023
	LLC Interests	Ownership %		LLC Interests	Ownership %
Number of LLC Interests held by Shake Shack Inc.	39,635,382	93.4	%	39,474,315	93.3	%

NOTE 10: INCOME TAXES

Shake Shack is the sole managing member of SSE Holdings and, as a result, consolidates 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 the Company, on a pro rata basis. The Company is subject to U.S. federal income taxes, in addition to state and local income taxes with respect to its 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. The Company is also subject to withholding taxes in foreign jurisdictions.

Effective income tax rates	19.0	%	(114.8)	%

The increase in the effective income tax rate for the thirteen weeks ended March 27, 2024 was primarily driven by the change in pre-tax income for the period compared to a pre-tax loss for the same period last year and the impact of discrete items which had a disproportionate effect on the minimal pre-tax loss in the prior year. Additionally, an increase in the Company's ownership interest in SSE Holdings increases its share of the taxable income (loss) of SSE Holdings.

The Company also recognizes 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. Refer to "Tax Receivable Agreement," herein for additional information.

	Thirteen Weeks Ended
	March 27 2024		March 29 2023
Deferred tax assets recognized under the Tax Receivable Agreement	$	303	$	129

The Company evaluates the realizability of its deferred tax assets on a quarterly basis and establishes 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 27, 2024, the Company concluded, based on the weight of all available positive and negative evidence, that all of its deferred tax assets (except for those deferred tax assets relating to certain state tax credits and net operating losses) are more likely than not to be realized. As such, no additional valuation allowance was recognized.

Tax Receivable Agreement

On February 4, 2015, the Company 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 the Company of 85% of the amount of any tax benefits that are actually realized, or in some cases are deemed to realize, as a result of (i) increases in the Company's share of the tax basis in the net assets of SSE Holdings resulting from any redemptions or exchanges of LLC Interests, (ii) tax basis

Shake Shack Inc. Form 10-Q | 19

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"). The Company expects to benefit from the remaining 15% of any tax benefits that may actually realize. The TRA Payments are not conditioned upon any continued ownership interest in SSE Holdings or the Company. 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.

Pursuant to the Company's election under Section 754 of the Internal Revenue Code (the "Code"), the Company expects to obtain an increase in its 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. The Company plans to make an election under Section 754 of the Code for each taxable year in which a redemption or exchange of LLC Interest occurs. The Company intends 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 would otherwise be paid 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.

There were no transactions subject to the Tax Receivable Agreement for which the Company did not recognize the related liability, as the Company concluded that it would have sufficient future taxable income to utilize all of the related tax benefits generated by all transactions that occurred during the thirteen weeks ended March 27, 2024 and March 29, 2023.

A summary of obligations under the Tax Receivable Agreement were as follows:

During the thirteen weeks ended March 27, 2024 and March 29, 2023, inclusive of interest, no payments were made to the parties to the Tax Receivable Agreement.

NOTE 11: EARNINGS (LOSS) PER SHARE

Basic earnings (loss) per share of Class A common stock is computed by dividing Net income (loss) attributable to Shake Shack Inc. by the weighted average number of shares of Class A common stock outstanding during the period. Diluted earnings (loss) per share of Class A common stock is computed by dividing Net income (loss) attributable 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.

Refer to Note 6, Debt, for additional information.

Shares of 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 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 anti-dilutive.

The Company also enters into long-term, exclusive contracts with certain vendors to supply food, beverages and paper goods, obligating the Company to purchase specified quantities.

Legal Contingencies

The Company is subject to various legal proceedings, claims and liabilities, involving employees and guests alike, which arise in the ordinary course of business and are generally covered by insurance.

OVERVIEW

Shake Shack serves modern, fun and elevated versions of American classics using only premium ingredients. We are known for our made-to-order 100% Angus beef burgers, crispy chicken, hand-spun milkshakes, house-made lemonades, beer, wine, and more. With our fine-dining roots and a commitment to crafting uplifting experiences, Shake Shack has become a cult-brand and created a new category, fine-casual.

Our mission is to Stand For Something Good in all aspects of our business, including the talented team we hire and train, the premium ingredients making up our menu, our community engagement and the design of our Shacks. Stand For Something Good is a call to action for all of our stakeholders — our team, guests, communities, suppliers and investors — and we actively invite them all to share in this philosophy with us. This commitment drives our integration into the local communities in which we operate and fosters a deep and lasting connection with our guests.

The following definitions apply to these terms as used herein:

"Average weekly sales" is calculated by dividing total Shack sales by the number of operating weeks for all Shacks in operation during the period. For Shacks that are not open for the entire period, fractional adjustments are made to the number of operating weeks open such that it corresponds to the period of associated sales.

"Same-Shack sales" represents Shack sales for the comparable Shack base, which is defined as the number of Company-operated Shacks open for 24 full fiscal months or longer. For consecutive days that Shacks were temporarily closed, the comparative period was also adjusted.

“System-wide sales” is an operating measure and consists of sales from Company-operated Shacks and licensed Shacks. The Company does not recognize the sales from licensed Shacks as revenue. Of these amounts, revenue is limited to licensing

Shake Shack Inc. Form 10-Q | 25

revenue based on a percentage of sales from licensed Shacks, as well as certain up-front fees, such as territory fees and opening fees.

Key Operating Metrics

Same-Shack sales for the thirteen weeks ended March 27, 2024 increased 1.6% compared to the same period last year, driven by a 3.7% increase in price mix partially offset by a 2.1% decrease in guest traffic. For the purpose of calculating same-Shack sales for the thirteen weeks ended March 27, 2024, Shack sales for 224 Shacks were included in the comparable Shack base.

Average weekly sales were $73,000 for the thirteen weeks ended March 27, 2024, which was flat compared to the same period last year, primarily driven by higher menu prices, partially offset by a decline in guest traffic.

System-wide sales for the thirteen weeks ended March 27, 2024 increased 12.3% to $443.3 million compared to the same period last year.

Digital sales for the thirteen weeks ended March 27, 2024 increased 15.3% to $103.2 million compared to the same period last year. Digital sales includes orders placed on the Shake Shack app, website and third-party delivery platforms, which represented 36.8% of Shack sales during the thirteen weeks ended March 27, 2024.

Development Highlights

During the thirteen weeks ended March 27, 2024, we opened four new Company-operated Shacks and four new licensed Shacks. There was one permanent licensed Shack closure in the first quarter of 2024.

The following table presents the Shacks opened during the thirteen weeks ended March 27, 2024:

(1)As a percentage of Shack sales.

Shack Sales

Shack sales represent the aggregate sales of food, beverages and Shake Shack branded merchandise at our Company-operated Shacks and gift card breakage income. Shack sales in any period are directly influenced by the number of operating weeks in such period and the total number of open Shacks.

	Dollar change compared to prior year	$	36,298
	Percentage change compared to prior year	14.9		%

Shack sales for the thirteen weeks ended March 27, 2024 increased 14.9% to $280.6 million versus the same period last year. The increase was primarily due to the opening of 39 new Company-operated Shacks between March 29, 2023 and March 27, 2024 which contributed $34.5 million and an increase in menu prices partially offset by a decline in guest traffic.

Shake Shack Inc. Form 10-Q | 27

Licensing Revenue

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

		Thirteen Weeks Ended
(dollar amounts in thousands)		March 27 2024			March 29 2023
Licensing revenue		$	9,952		$	9,024
	Percentage of Total revenue	3.4		%	3.6		%

	Percentage change compared to prior year	10.3		%

Licensing revenue for the thirteen weeks ended March 27, 2024 increased 10.3% to $10.0 million versus the same period last year. The increase was primarily due to the opening of 37 net new licensed Shacks between March 29, 2023 and March 27, 2024 which contributed $1.6 million to Licensing revenue, partially offset by a decline in sales at existing licensed Shacks, primarily in China and the Middle East.

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, impacted by menu mix, channel mix and fluctuations in commodity costs, as well as geographic scale and proximity.

		Thirteen Weeks Ended
(dollar amounts in thousands)		March 27 2024			March 29 2023

	Percentage of Shack sales	28.6		%	29.4		%
	Dollar change compared to prior year	$	8,481
	Percentage change compared to prior year	11.8		%

Food and paper costs for the thirteen weeks ended March 27, 2024 increased 11.8% to $80.3 million versus the same period last year. The increase was primarily due to the opening of 39 new Company-operated Shacks between March 29, 2023 and March 27, 2024, which contributed approximately $9.0 million.

As a percentage of Shack sales, the decrease in Food and paper costs for the thirteen weeks ended March 27, 2024 was primarily driven by menu price increases partially offset by the increases in commodities costs, mainly beef and fries and increases in marketing promotions.

Labor and Related Expenses

Labor and related expenses include 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, labor costs should 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 Company-operated Shacks.

	Percentage change compared to prior year	9.8		%

Labor and related expenses for the thirteen weeks ended March 27, 2024 increased 9.8% to $81.5 million versus the same period last year. The increase was primarily due to the opening of 39 new Company-operated Shacks between March 29, 2023 and March 27, 2024.

As a percentage of Shack sales, the decrease in Labor and related expenses for the thirteen weeks ended March 27, 2024 was primarily due to labor efficiencies partially offset by additional expenses from the opening of 39 new Company-operated Shacks between March 29, 2023 and March 27, 2024.

Other Operating Expenses

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

	Percentage change compared to prior year	19.8		%

Other operating expenses for the thirteen weeks ended March 27, 2024 increased 19.8% to $41.9 million versus the same period last year. The increase was primarily driven by higher facilities costs, mainly professional services, due to the opening of 39 new Company-operated Shacks between March 29, 2023 and March 27, 2024, as well as increases in transaction fees associated with higher sales and marketing costs.

As a percentage of Shack sales, the increase in Other operating expenses for the thirteen weeks ended March 27, 2024 was primarily due to increases in delivery commissions associated with higher delivery sales and marketing spend, partially offset by lower utility costs.

Occupancy and Related Expenses

Occupancy and related expenses consist of Shack-level occupancy expenses (including rent, common area expenses and certain local taxes), and exclude occupancy expenses associated with unopened Shacks, which are recorded separately in Pre-opening costs.

As a percentage of Shack sales, the increase in Occupancy and related expenses for the thirteen weeks ended March 27, 2024 were primarily due to higher variable rent and occupancy taxes.

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.

		Thirteen Weeks Ended
(dollar amounts in thousands)		March 27 2024			March 29 2023

	Percentage change compared to prior year	14.8		%

General and administrative expenses for the thirteen weeks ended March 27, 2024 increased 14.8% to $35.9 million versus the same period last year. The increase was primarily due to increases in wages and other team costs to support our Shack growth, costs related to the restatement of prior periods included in the fiscal 2023 Form 10-K, professional fees related to non-recurring matters, as well as investments in marketing and technology initiatives, partially offset by the absence of one-time legal settlements compared to the prior year period.

As a percentage of Total revenue, General and administrative expenses was flat at 12.4% for the thirteen weeks ended March 27, 2024 and March 29, 2023, which was primarily due to sales leverage partially offset by the aforementioned items.

Depreciation and Amortization Expense

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

		Thirteen Weeks Ended

	Percentage change compared to prior year	19.3		%

Depreciation and amortization expense for the thirteen weeks ended March 27, 2024 increased 19.3% to $25.4 million versus the same period last year. The increase was predominantly due to incremental depreciation of capital expenditures related to the opening of 39 new Company-operated Shacks and technology projects placed into service between March 29, 2023 and March 27, 2024.

Pre-Opening Costs

Pre-opening costs consist primarily of occupancy, manager and team member wages, cookware, travel and lodging costs for our opening training team and other supporting team members, marketing expenses, legal fees and inventory costs incurred prior to the opening of a Shack. All such costs incurred prior to the opening of a 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 Company-operated Shack openings and the specific pre-opening costs incurred for each Company-operated Shack. Additionally, Company-operated Shack openings in new geographic markets may initially experience higher pre-opening costs

30 | Shake Shack Inc. Form 10-Q

than our established geographic markets, 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.

Pre-opening costs for the thirteen weeks ended March 27, 2024 decreased 22.6% to $2.8 million versus the same period last year. The decrease was primarily due to a reduction in wages and team costs as we standardize the training process for unopened Shacks partially offset by an increase in legal costs.

Impairment and Loss on Disposal of Assets

Impairment and loss on disposal of assets primarily consists of 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 which primarily consists of furniture, equipment and fixtures that were replaced in the normal course of business.

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 us. We are also subject to withholding taxes in foreign jurisdictions.

	Percentage of Total revenue	0.2		%	0.3		%
	Dollar change compared to prior year	$	(349)
	Percentage change compared to prior year	(40.3)		%

Our effective income tax rates for the thirteen weeks ended March 27, 2024 and March 29, 2023 were 19.0% and (114.8)%, respectively. The increase was primarily driven by the change in pre-tax income for the period compared to a pre-tax loss for the same period last year and the impact of discrete items which had a disproportionate effect on the minimal pre-tax loss in the prior year. Additionally, an increase in the Company's ownership interest in SSE Holdings increases its share of the taxable income (loss) of SSE Holdings. Our weighted-average ownership interest in SSE Holdings was 93.3% and 93.2%, respectively, for the thirteen weeks ended March 27, 2024 and March 29, 2023.

Net Income (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 (loss) to Shake Shack Inc. and the non-controlling interest holders.

Net income (loss) attributable to non-controlling interests for the thirteen weeks ended March 27, 2024 improved to income of $0.2 million from a loss of $0.1 million in the same period last year. The improvement for the thirteen weeks ended March 27, 2024 was primarily due to improved net results compared to the same period last year, partially offset by a decrease in the non-controlling interest holders' weighted average ownership, which was 6.7% and 6.8%, respectively for the thirteen weeks ended March 27, 2024 and March 29, 2023.

NON-GAAP FINANCIAL MEASURES

To supplement the Condensed Consolidated Financial Statements, which are prepared and presented in accordance with accounting principles generally accepted in the United States of America ("GAAP"), we use the following non-GAAP financial measures: Restaurant-level profit, Restaurant-level profit margin, EBITDA, adjusted EBITDA, adjusted EBITDA margin, adjusted pro forma net income (loss) and adjusted pro forma earnings (loss) per fully exchanged and diluted share (collectively the "non-GAAP financial measures").

Restaurant-Level Profit

Restaurant-level profit, formerly referred to as Shack-level operating profit, is defined as Shack sales less Shack-level operating expenses which include 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, Restaurant-level profit and Restaurant-level profit margin are supplemental measures of operating performance that we believe are useful measures to evaluate the performance and profitability of our Shacks. Additionally, Restaurant-level profit and Restaurant-level profit margin are key metrics used internally by our management to develop internal budgets and forecasts, as well as assess the performance of our Shacks relative to budget and against prior periods. It is also used to evaluate team member compensation as it serves as a metric in certain of our performance-based team member bonus arrangements. We believe the presentation of Restaurant-level profit and Restaurant-level profit margin provides investors with a supplemental view of our operating performance that can provide meaningful insights to the underlying operating performance of our Shacks, as these measures depict the operating results that are directly impacted by our Shacks and exclude items that may not be indicative of, or are unrelated to, the ongoing operations of our Shacks. It may also assist investors to evaluate our performance relative to peers of various sizes and maturities and provides greater transparency with respect to how our management evaluates our business, as well as our financial and operational decision-making.

Limitations of the Usefulness of this Measure

Restaurant-level profit and Restaurant-level profit margin may differ from similarly titled measures used by other companies due to different methods of calculation. Presentation of Restaurant-level profit and Restaurant-level 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. Restaurant-level 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 our Shacks. Therefore, this measure may not provide a complete understanding of the operating results of our Company as a whole and Restaurant-level profit and Restaurant-level profit margin should be reviewed in conjunction with our GAAP financial results. A reconciliation of Restaurant-level profit to Income (loss) from operations, the most directly comparable GAAP financial measure, is as follows.

EBITDA and Adjusted EBITDA

EBITDA is defined as Net income (loss) before Interest expense (net of interest income), Income tax expense and Depreciation and amortization expense. Adjusted EBITDA is defined as EBITDA (as defined above) excluding equity-based compensation expense, Impairment and loss on disposal of assets, amortization of cloud-based software implementation costs, as well as certain non-recurring items that we do not believe directly reflect our core operations and may not be indicative of our 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 we believe are useful measures to facilitate comparisons to historical performance and competitors' operating results. Adjusted EBITDA is a key metric used internally by our management to develop internal budgets and forecasts and also serves as a metric in our performance-based equity incentive programs and certain of our bonus arrangements. We believe presentation of EBITDA and adjusted EBITDA provides investors with a supplemental view of our operating performance that facilitates analysis and comparisons of our ongoing business operations because they exclude items that may not be indicative of our 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 our performance and should be reviewed in conjunction with our 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 (Loss) and Adjusted Pro Forma Earnings (Loss) Per Fully Exchanged and Diluted Share

Adjusted pro forma net income (loss) 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 do not believe are directly related to our core operations and may not be indicative of our recurring business operations. Adjusted pro forma earnings (loss) 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 the dilutive effect of outstanding equity-based awards.

How These Measures Are Useful

When used in conjunction with GAAP financial measures, adjusted pro forma net income (loss) and adjusted pro forma earnings (loss) 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 (loss) and adjusted pro forma earnings (loss) per fully exchanged and diluted share may differ from similarly titled measures used by other companies due to different methods of calculation. Presentation of adjusted pro forma net income (loss) and adjusted pro forma earnings (loss) 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, they do not account for the earnings attributable to the non-controlling interest holders and therefore do not provide a complete understanding of the Net income (loss) attributable to Shake Shack Inc. Adjusted pro forma net income (loss) and adjusted pro forma earnings (loss) per fully exchanged and diluted share should be evaluated in conjunction with our GAAP financial results.

LIQUIDITY AND CAPITAL RESOURCES

Sources and Uses of Cash

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. As of March 27, 2024, we maintained a Cash and cash equivalents balance of $260.2 million and a short-term investments balance of $24.6 million within Marketable securities. In March 2021, we issued 0% Convertible Senior Notes (“Convertible Notes”), and received $243.8 million of proceeds, net of discounts. Refer to Note 6, Debt, in the accompanying Condensed Consolidated Financial Statements, for additional information.

On June 7, 2021, 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 technology infrastructure to support our home office, Shake Shack locations, and digital strategy.

In addition, we are obligated to make payments to certain members of SSE Holdings under the Tax Receivable Agreement. As of March 27, 2024, such obligations totaled $236.7 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 payments under the Tax Receivable Agreement. 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.

We believe our existing cash and cash equivalents balances and cash from operations 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.

Shake Shack Inc. Form 10-Q | 37

Operating Activities

For the thirteen weeks ended March 27, 2024, net cash provided by operating activities was $30.7 million compared to $19.8 million for the thirteen weeks ended March 29, 2023, an increase of $10.8 million. The increase was primarily driven by a $7.5 million improvement in net results after excluding non-cash charges as well as changes in working capital of $3.3 million. The changes in working capital included an increase in liabilities related to general business operations as well as the timing and payments related to accruals and legal settlements, partially offset by a decrease in liabilities related to bonus arrangements.

Investing Activities

For the thirteen weeks ended March 27, 2024, net cash provided by investing activities was $11.3 million compared to $46.5 million for the thirteen weeks ended March 29, 2023, an decrease of $35.2 million. This decrease was primarily due to a net decrease in marketable securities activity as a result of the sale of equity securities of $81.5 million in the prior year, partially offset by maturities of held-to-maturity marketable securities in the current year of $44.4 million.

Financing Activities

For the thirteen weeks ended March 27, 2024, net cash used in financing activities was $6.4 million compared to $3.4 million for the thirteen weeks ended March 29, 2023, an increase of $3.0 million. This increase was primarily due to an increase in withholding taxes related to net settled equity awards.

Convertible Notes

In March 2021, we issued $250.0 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. 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 Class A common stock or a combination of cash and shares of Class A common stock, at our election. Refer to Note 6, Debt, in the accompanying Condensed Consolidated Financial Statements, for additional information.

Revolving Credit Facility

In August 2019, we entered into a Revolving Credit Facility, which matures in March 2026 and permits borrowings up to $50.0 million, with the ability to increase available borrowings up to an additional $100.0 million, 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 June 2023, the Company entered into the fourth amendment to the Revolving Credit Facility ("Fourth Amendment"), which, among other things, modified the benchmark interest rate to either: (i) the base rate plus applicable margin ranging from 0.0% to 1.5% or (ii) the Secured Overnight Financing Rate (“SOFR”) plus applicable margin ranging from 1.0% to 2.5%, in each case depending on the net lease adjusted leverage ratio. As of March 27, 2024 and December 27, 2023, 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, as well as other customary affirmative and negative covenants. As of March 27, 2024, we were in compliance with all covenants.

Contractual Obligations

Material contractual obligations arising in the normal course of business primarily consist of operating and finance lease obligations, long-term debt, liabilities under the Tax Receivable Agreement and purchase obligations. The timing and nature of these commitments are expected to have an impact on our liquidity and capital requirements in future periods. Refer to Note 6, Debt and Note 7, Leases, in the accompanying Condensed Consolidated Financial Statements included in Part I, Item 1 for additional information relating to our long-term debt and operating and financing leases.

38 | Shake Shack Inc. Form 10-Q

Liabilities under the Tax Receivable Agreement include amounts to be paid to the non-controlling interest holders, assuming we will have sufficient taxable income over the term of the Tax Receivable Agreement to utilize the related tax benefits. Refer to Note 10, Income Taxes, and Note 13, Commitments and Contingencies, in the accompanying Condensed Consolidated Financial Statements included in Part I, Item 1, for additional information relating to our Tax Receivable Agreement and related liabilities.

Purchase obligations include all 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. The majority of our purchase obligations are due within the next 12 months.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

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 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 27, 2023.

Recently Issued Accounting Pronouncements

Refer to Note 2, Summary of Significant Accounting Policies under Part I, Item 1 of this Form 10-Q.

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 27, 2023.

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 the Securities Exchange Act of 1934 (the "Exchange Act")) as of the end of the period covered by this report. 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.

Based upon the evaluation of our disclosure controls and procedures as of March 27, 2024, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not effective due to the existence of the material weakness in our internal control over financial reporting identified in fiscal 2023, as described below.

Shake Shack Inc. Form 10-Q | 39

PREVIOUSLY REPORTED MATERIAL WEAKNESS

As previously disclosed in Item 9A. “Controls and Procedures” on Form 10-K for the year ended December 27, 2023, management identified a material weakness in our internal control over financial reporting related to the calculation of state deferred taxes and the related income tax expense (benefit). Specifically, the internal controls in place with respect to the calculation of state deferred taxes and the related income tax expense (benefit) were not designed appropriately. The material weakness existed as of December 27, 2023 and prior periods.

Management identified and reported this weakness to both our audit committee and Ernst & Young LLP, our independent registered public accounting firm, immediately upon identification. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues have been detected. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under potential future conditions, regardless of how remote.

REMEDIATION STATUS OF MATERIAL WEAKNESS

We are designing and implementing measures to remediate the material weakness noted above and to enhance our internal control over financial reporting. As of the filing of this Quarterly Report on Form 10-Q, we have established a Steering Committee with representatives from key departments within our Finance organization as well as representatives from IT and Securities Counsel and began remediation activities. We have hired a Head of Tax with over 20 years of tax leadership experience including working with Up-C structures, enhancing controls, processes, and tax technology. Additionally, we are currently supplementing our tax resources through the use of third-party tax consultants and intend to utilize the third-party tax consultants, under the supervision of management, throughout the remediation process. In addition, we are in the process of developing enhanced management review control procedures over the calculation of state deferred taxes and the related income tax expense (benefit).

The actions that we are taking are subject to ongoing senior management review, as well as oversight of the audit committee of our board of directors. The material weakness cannot be considered remediated until the applicable remedial controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively. We will continue to monitor the design and effectiveness of these and other processes, procedures and controls and make any further changes management deems appropriate.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

Except as described above, there were no changes to our internal control over financial reporting that occurred during the quarter ended March 27, 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

NATURE OF OPERATIONS

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"). Shake Shack Inc. is the sole managing member of SSE Holdings and, as sole managing member, the Company operates and controls all of the business and affairs of SSE Holdings. As a result, the Company consolidates the financial results of SSE Holdings and reports a non-controlling interest representing the economic interest in SSE Holdings held by the other members of SSE Holdings. As of March 27, 2024 the Company owned 93.4% 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.

The Company operates and licenses Shake Shack restaurants ("Shacks"), which serve burgers, chicken, hot dogs, crinkle cut fries, shakes, frozen custard, beer, wine and more. As of March 27, 2024, there were 525 Shacks in operation system-wide, of which 299 were Company-operated Shacks and 226 were licensed Shacks.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Mar. 27, 2024

Accounting Policies [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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 its Annual Report on Form 10-K for the fiscal year ended December 27, 2023 ("2023 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 the rules and regulations of the Securities and Exchange Commission. These interim Condensed Consolidated Financial Statements should be read in conjunction with the consolidated financial statements and related notes thereto included in its 2023 Form 10-K. In the Company's opinion, all adjustments, which are normal and recurring in nature, necessary for a fair presentation of the 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 the Company has the majority economic interest in SSE Holdings and, as the sole managing member, has 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, the Company consolidates SSE Holdings. The assets and liabilities of SSE Holdings represent substantially all of the Company's consolidated assets and liabilities with the exception of certain deferred taxes and liabilities under the Tax Receivable Agreement. As of March 27, 2024 and December 27, 2023, the net assets of SSE Holdings were $394,523 and $388,250, respectively. The assets of SSE Holdings are subject to certain restrictions in SSE Holdings' revolving credit agreement.

Fiscal Year

The Company operates on a 52/53 week fiscal year ending on the last Wednesday of December. Fiscal 2024 contains 52 weeks and ends on December 25, 2024. Fiscal 2023 contained 52 weeks and ended on December 27, 2023. 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 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

The Company reviewed all recently issued accounting pronouncements and concluded that they were not applicable or not expected to have a significant impact on its Condensed Consolidated Financial Statements.

Revenue primarily 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 the Company expects to be entitled to in exchange for those goods or services.

Shack Sales

Revenue from Shack sales is recognized when payment is tendered at the point of sale, net of discounts as the performance obligation has been satisfied at that time. Sales tax collected from guests is excluded from Shack sales and the obligation is included as sales tax payable until the taxes are remitted to the appropriate taxing authorities.

Delivery services are fulfilled by third-party delivery partners whether ordered through the Shack app, website ("Company-owned platforms") or through third-party delivery platforms. Revenue from orders through Company-owned platforms includes delivery fees and is recognized when the delivery partner transfers the order to the guest as the Company controls the delivery. For these sales, the Company receives payment directly from the guest at the time of sale. Revenue from orders through third-party delivery platforms is recognized when the order is transferred to the third-party delivery partner and excludes delivery fees collected by the delivery partner as the Company does not control the delivery. The Company receives payment from the delivery partner subsequent to the transfer of the order and the payment terms are short-term in nature. For all delivery sales, the Company is considered the principal and recognizes revenue on a gross basis.

The Company sells gift cards which do not have expiration dates. Revenue from gift cards is recognized when gift cards are redeemed by the customer or, in the event a gift card is not expected to be redeemed, in proportion to actual redemptions of gift cards ("gift card breakage"). The gift card breakage rate is determined from historical gift card redemption patterns. Gift card breakage income for the thirteen weeks ended March 27, 2024 and March 29, 2023 was $134 and $106, respectively. Gift card breakage income is included in Shack sales in the Condensed Consolidated Statements of Income (Loss).

Licensing Revenue

Licensing revenue includes 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 good or service transferred to the licensee 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 license and considered one performance obligation per Shack.

The Company determines the transaction price for each contract, which is comprised of the initial territory fee and an estimate of the total Shack opening fees the Company expects to be entitled to. The calculation of total Shack opening fees requires judgment, as it is based on an estimated number of Shacks the Company expects the licensee to open. The transaction price is then allocated equally to each Shack expected to open. The performance obligation is satisfied over time, starting when a Shack opens through the end of the license term for the related Shack, therefore 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 license agreement and payment for the Shack opening fees is received either in advance of or upon opening the related Shack. These payments are initially deferred and

recognized in revenue as the performance obligations are satisfied. Revenue from sales-based royalties is recognized as the related sales occur.

Revenue disaggregated by type was as follows:

	Thirteen Weeks Ended
	March 27 2024		March 29 2023
Shack sales	$	280,552	$	244,254
Licensing revenue:
Sales-based royalties	9,633		8,778
Initial territory and opening fees	319		246
Total revenue	$	290,504	$	253,278

The aggregate amount of the transaction price allocated to performance obligations that were unsatisfied or partially unsatisfied as of March 27, 2024 was $23,370. The Company expects 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.

Convertible Notes

The Company's $250,000 aggregate principal amount of 0% Convertible Senior Notes due 2028 (“Convertible Notes”) will mature on March 1, 2028, unless earlier converted, redeemed or repurchased in certain circumstances. Upon conversion, the Company pays or delivers, as the case may be, cash, shares of Class A common stock or a combination of cash and shares of Class A common stock, at the Company's 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 the Company's 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 one thousand dollar 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 the Company calls 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 Class A common stock per one thousand dollar principal amount of Convertible Notes, which is equivalent to an initial conversion price of approximately $170.42 per share of Class A common stock. The fair value of the Convertible Notes was approximately $226,795 and $205,000, respectively, as of March 27, 2024 and December 27, 2023, 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.

Revolving Credit Facility

The Company maintains a revolving credit facility agreement ("Revolving Credit Facility") which permits borrowings up to $50,000 with the ability to increase available borrowings up to an additional $100,000, subject to satisfaction of certain conditions. The Revolving Credit Facility has a maturity date of March 5, 2026.

In June 2023, the Company entered into the fourth amendment to the Revolving Credit Facility ("Fourth Amendment"), which, among other things, modified the benchmark interest rate to either: (i) the base rate plus applicable margin ranging from 0.0% to 1.5% or (ii) the Secured Overnight Financing Rate (“SOFR”) plus applicable margin ranging from 1.0% to 2.5%, in each case

dependent upon the net lease adjusted leverage ratio. As of March 27, 2024 and December 27, 2023, 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 the Company to comply with maximum net lease adjusted leverage and minimum fixed charge coverage ratios, as well as other customary affirmative and negative covenants. As of March 27, 2024, the Company was in compliance with all covenants.

The Revolving Credit Facility also permits the issuance of letters of credit upon our request of up to $15,000. As of March 27, 2024 and December 27, 2023, the Company had outstanding letters of credit of $3,310 and $3,147, respectively, in connection with the Revolving Credit Facility.

LEASES

Nature of Leases

Shake Shack currently leases all of its Company-operated Shacks, the home office and certain equipment under various non-cancelable lease agreements that expire on various dates through 2045. The Company evaluates 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. The Company evaluates whether it controls the use of the asset, which is determined by assessing whether substantially all economic benefit from the use of the asset is obtained, and whether the Company has the right to direct the use of the asset. If these criteria are met, the Company has identified a lease within the contract, and therefore a right of use asset and lease liability are recorded on the Condensed Consolidated Balance Sheet. Upon possession of a leased asset, the Company determines whether the lease is an operating or finance lease. All of the Company's real estate leases are classified as operating leases and most equipment leases are classified as finance leases.

Generally, 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 the Company would exercise the renewal options. Real estate leases typically contain fixed minimum rent payments and/or contingent rent payments which are 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.

For operating leases, fixed lease payments are recognized as operating lease costs on a straight-line basis over the lease term within the Condensed Consolidated Statements of Income (Loss) in the following line items. Lease expense incurred before a Shack opens is recorded in Pre-opening costs. Once a Company-operated Shack opens, the straight-line lease expense and contingent rent, if applicable, are recorded in Occupancy and related expenses. Many of these leases also require the Company to pay real estate taxes, common area maintenance costs and other occupancy costs which are included in Occupancy and related expenses. Finance leases are recognized in depreciation expense on a straight-line basis over the remaining lease term, along with recognition of interest expense associated with accretion of the lease liability.

For both operating and finance leases that contain lease and non-lease components, the components are combined and accounted for as a single lease component. Variable lease costs for both operating and finance leases, if any, are recognized as incurred. Leases with a term of 12 months or less are deemed short-term and are not recognized on the Condensed Consolidated Balance Sheets. Fixed lease payments for short-term leases are recognized on a straight-line basis over the lease term.

The Company calculates operating lease assets and lease liabilities as the present value of fixed lease payments over the reasonably certain lease term beginning at the commencement date. The Company uses its incremental borrowing rate ("IBR") in determining the present value of future lease payments as there are no explicit rates provided in the leases. The IBR 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 IBR is the Company's credit rating and is subject to judgment. The credit rating used to develop the IBR is determined by utilizing the credit ratings of other public companies with similar financial information as SSE Holdings.

The Company expends cash for leasehold improvements to build out and equip leased properties. Generally, a portion of the leasehold improvements and building costs are reimbursed by the landlords through landlord incentives pursuant to agreed-upon terms in the lease agreements. Landlord incentives usually take the form of cash, full or partial credits against future minimum or contingent rents otherwise payable by the Company, or a combination thereof. In most cases, landlord incentives are received after the Company takes possession of the property and as milestones are met during the construction of the property. The Company includes these amounts in the measurement of the initial operating lease liability, and lease asset.

NON-CONTROLLING INTERESTS

NON-CONTROLLING INTERESTS

Shake Shack is the primary beneficiary and sole managing member of SSE Holdings and, as a result, consolidates the financial results of SSE Holdings. The Company reports 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, the Company will receive a corresponding number of LLC Interests, increasing the total ownership interest in SSE Holdings. Changes in the ownership interest in SSE Holdings while the Company retains its 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:

	March 27, 2024			December 27, 2023
	LLC Interests	Ownership %		LLC Interests	Ownership %
Number of LLC Interests held by Shake Shack Inc.	39,635,382	93.4	%	39,474,315	93.3	%

Income Tax Disclosure [Abstract]

INCOME TAXES

INCOME TAXES

Shake Shack is the sole managing member of SSE Holdings and, as a result, consolidates 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 the Company, on a pro rata basis. The Company is subject to U.S. federal income taxes, in addition to state and local income taxes with respect to its 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. The Company is also subject to withholding taxes in foreign jurisdictions.

Effective Income Tax Rates

The following table presents the Company’s effective income tax rates:

	Thirteen Weeks Ended
	March 27 2024		March 29 2023
Effective income tax rates	19.0	%	(114.8)	%

The increase in the effective income tax rate for the thirteen weeks ended March 27, 2024 was primarily driven by the change in pre-tax income for the period compared to a pre-tax loss for the same period last year and the impact of discrete items which had a disproportionate effect on the minimal pre-tax loss in the prior year. Additionally, an increase in the Company's ownership interest in SSE Holdings increases its share of the taxable income (loss) of SSE Holdings.

The Company's weighted average ownership interest in SSE Holdings was as follows:

	Thirteen Weeks Ended
	March 27 2024		March 29 2023
Shake Shack's weighted average ownership percentages	93.3	%	93.2	%

Deferred Tax Assets and Liabilities

The Company acquires LLC Interests in connection with the redemption of LLC Interests and activity relating to its stock compensation plan and recognizes deferred tax assets associated with the basis difference in its investment in SSE Holdings upon acquisition of these LLC Interests.

The following table summarizes the LLC Interests acquired by the Company:

	Thirteen Weeks Ended
	March 27 2024	March 29 2023
LLC Interests activity under the Company's stock compensation plan	127,567	94,907
LLC Interests activity from redemptions of LLC Interests	33,500	25,000
Total LLC Interests acquired by the Company	161,067	119,907

Deferred tax assets related to the basis difference in the Company's investment in SSE Holdings were as follows:

	Thirteen Weeks Ended
	March 27 2024		March 29 2023
Deferred tax assets recognized upon acquisition of LLC Interests	$	3,314	$	824

	March 27 2024		December 27 2023
Total deferred tax assets related to the acquisition of LLC Interests	$	95,228	$	90,419

The Company also recognizes 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. Refer to "Tax Receivable Agreement," herein for additional information.

	Thirteen Weeks Ended
	March 27 2024		March 29 2023
Deferred tax assets recognized under the Tax Receivable Agreement	$	303	$	129

The Company evaluates the realizability of its deferred tax assets on a quarterly basis and establishes 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 27, 2024, the Company concluded, based on the weight of all available positive and negative evidence, that all of its deferred tax assets (except for those deferred tax assets relating to certain state tax credits and net operating losses) are more likely than not to be realized. As such, no additional valuation allowance was recognized.

Tax Receivable Agreement

On February 4, 2015, the Company 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 the Company of 85% of the amount of any tax benefits that are actually realized, or in some cases are deemed to realize, as a result of (i) increases in the Company's 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"). The Company expects to benefit from the remaining 15% of any tax benefits that may actually realize. The TRA Payments are not conditioned upon any continued ownership interest in SSE Holdings or the Company. 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.

Pursuant to the Company's election under Section 754 of the Internal Revenue Code (the "Code"), the Company expects to obtain an increase in its 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. The Company plans to make an election under Section 754 of the Code for each taxable year in which a redemption or exchange of LLC Interest occurs. The Company intends 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 would otherwise be paid 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.

There were no transactions subject to the Tax Receivable Agreement for which the Company did not recognize the related liability, as the Company concluded that it would have sufficient future taxable income to utilize all of the related tax benefits generated by all transactions that occurred during the thirteen weeks ended March 27, 2024 and March 29, 2023.

A summary of obligations under the Tax Receivable Agreement were as follows:

	Thirteen Weeks Ended
	March 27 2024		March 29 2023
Additional liabilities recognized under the Tax Receivable Agreement	$	1,115	$	472

	March 27 2024		December 27 2023
Total obligations under the Tax Receivable Agreement	$	236,728	$	235,613

During the thirteen weeks ended March 27, 2024 and March 29, 2023, inclusive of interest, no payments were made to the parties to the Tax Receivable Agreement.

Earnings Per Share [Abstract]

EARNINGS (LOSS) PER SHARE

EARNINGS (LOSS) PER SHARE

Basic earnings (loss) per share of Class A common stock is computed by dividing Net income (loss) attributable to Shake Shack Inc. by the weighted average number of shares of Class A common stock outstanding during the period. Diluted earnings (loss) per share of Class A common stock is computed by dividing Net income (loss) attributable 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.

The following table sets forth reconciliations of the numerators and denominators used to compute basic and diluted earnings (loss) per share of Class A common stock (in thousands, except per share amounts):

			Thirteen Weeks Ended
			March 27 2024		March 29 2023

Earnings (loss) per share of Class A common stock—basic			$	0.05	$	(0.04)
Earnings (loss) per share of Class A common stock—diluted			$	0.05	$	(0.04)

The effect of potential share settlement of the Convertible Notes outstanding for the period is included as potentially dilutive shares of Class A common stock under application of the if-converted method in the computation of diluted earnings (loss) per share, except when the effect would be anti-dilutive. Refer to Note 6, Debt, for additional information.

Shares of 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 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 anti-dilutive.

The following table presents potentially dilutive securities excluded from the computations of diluted earnings (loss) per share of Class A common stock:

	Thirteen Weeks Ended
	March 27 2024		March 29 2023
Stock options	—		128,656	(2)

COMMITMENTS AND CONTINGENCIES

COMMITMENTS AND CONTINGENCIES

Lease Commitments

The Company is obligated under various operating leases for Shacks and the home office space, expiring in various years through 2045. Under certain of these leases, the Company is liable for contingent rent based on a percentage of sales in excess of specified thresholds and typically responsible for its proportionate share of real estate taxes, common area maintenance costs and other occupancy costs. Refer to Note 7, Leases, for additional information.

Certain leases require the Company to obtain letters of credit. As of March 27, 2024, the Company held three letters of credit, one for $402, which expires in August 2024 and renews automatically for one-year periods through January 2034, one for $163, which expires in December 2024 and renews automatically for one-year periods through December 2029 and one for $130 which expires in February 2026.

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. The Company also enters into long-term, exclusive contracts with certain vendors to supply food, beverages and paper goods, obligating the Company to purchase specified quantities.

Legal Contingencies

The Company is subject to various legal proceedings, claims and liabilities, involving employees and guests alike, which arise in the ordinary course of business and are generally covered by insurance. As of March 27, 2024, the amount of the ultimate liability with respect to these matters was not material.

Liabilities under Tax Receivable Agreement

The Company is a party to the Tax Receivable Agreement under which it is contractually committed to pay certain of the members of SSE Holdings 85% of the amount of any tax benefits that are actually realized, or in some cases are deemed to realize, as a result of certain transactions.

The Company is 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 the Company does not generate sufficient taxable income in the aggregate over the term of the Tax Receivable Agreement to utilize the tax benefits, then it would not be required to make the related TRA Payments.

The Company recognizes liabilities relating to the obligations under the Tax Receivable Agreement if concluding that it is probable that it would have sufficient future taxable income over the term of the Tax Receivable Agreement to utilize the related tax benefits. Refer to Note 10, Income Taxes, for additional information relating to the Tax Receivable Agreement.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

3 Months Ended

Mar. 27, 2024

Accounting Policies [Abstract]

Basis of Presentation

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 its Annual Report on Form 10-K for the fiscal year ended December 27, 2023 ("2023 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 the rules and regulations of the Securities and Exchange Commission. These interim Condensed Consolidated Financial Statements should be read in conjunction with the consolidated financial statements and related notes thereto included in its 2023 Form 10-K. In the Company's opinion, all adjustments, which are normal and recurring in nature, necessary for a fair presentation of the 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 the Company has the majority economic interest in SSE Holdings and, as the sole managing member, has 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, the Company consolidates SSE Holdings. The assets and liabilities of SSE Holdings represent substantially all of the Company's consolidated assets and liabilities with the exception of certain deferred taxes and liabilities under the Tax Receivable Agreement. As of March 27, 2024 and December 27, 2023, the net assets of SSE Holdings were $394,523 and $388,250, respectively. The assets of SSE Holdings are subject to certain restrictions in SSE Holdings' revolving credit agreement.

Fiscal Year

Fiscal Year

The Company operates on a 52/53 week fiscal year ending on the last Wednesday of December. Fiscal 2024 contains 52 weeks and ends on December 25, 2024. Fiscal 2023 contained 52 weeks and ended on December 27, 2023. Unless otherwise stated, references to years in this report relate to fiscal years.

Use of Estimates

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 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.
