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 31, 2025 ("2025 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 SEC. These interim Condensed Consolidated Financial Statements should be read in conjunction with the consolidated financial statements and related notes thereto included in the Company's 2025 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 the 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 September 30, 2026 and December 31, 2025, the net assets of SSE Holdings were $555,256 and $500,732, respectively. The assets of SSE Holdings are subject to certain restrictions in SSE Holdings' revolving credit agreement.

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.

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

12 |Shake Shack Inc. Form 10-Q

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 thefive business day period after anyten 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 $236,000 and $236,875, respectively, as of September 30, 2026 and December 31, 2025, 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.

In July 2025, the Company entered into the sixth amendment to the Revolving Credit Facility ("Sixth Amendment"), which, among other things, extends the maturity date until the earlier of (a) February 28, 2028, or (b) the date that is 91 days prior to the scheduled maturity date of any Convertible Notes outstanding at any time.

Outstanding borrowings under the Revolving Credit Facility bear interest at 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 September 30, 2026 and December 31, 2025, 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 September 30, 2026, 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 September 30, 2026 and December 31, 2025, the Company had outstanding letters of credit of $4,917 and $4,839, respectively, in connection with the Revolving Credit Facility.

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 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 SSE Holdings, LLC membership interests ("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 aone-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:

The weighted average ownership percentages for the applicable reporting periods are used to attribute Net income and Other comprehensive income to the non-controlling interest holders and were as follows:

NOTE 10: INCOME TAXES

Shake Shack is the sole managing member of SSE Holdings, which is classified as a partnership for U.S federal and most applicable state and local income tax purposes. As the managing member, the Company consolidates SSE Holdings financial results. As a partnership, SSE Holdings is not subject to U.S. federal and certain state and local income taxes. Instead, any taxable income or loss generated by SSE Holdings is allocated to its members, including the Company, on a pro rata basis. The Company is subject to U.S. federal, state and local income taxes with respect to its allocable share of taxable income or loss from 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.

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.

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 September 30, 2026, 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.

One Big Beautiful Bill Act

On July 4, 2025, bill H.R. 1, commonly referred to as the "One Big Beautiful Bill Act" or "OBBBA," was signed into law, with certain provisions effective in 2025 and others in 2026. The Act provides for changes to U.S. federal tax law, including the expensing of U.S. research expenditures and certain eligible capital expenditures, among other provisions. The Company has recognized the effects of the OBBBA provisions in its financial results to the extent they are applicable to the thirty-nine weeks ended September 30, 2026.

Tax Receivable Agreement

On February 4, 2015, the Company entered into a tax receivable agreement with certain then-existing non-controlling members of SSE Holdings (the "Tax Receivable Agreement"). This agreement obligates the Company to pay the non-controlling interest holders 85% of any tax benefits that the Company may actually realize, or be deemed to realize, from (i) increases in the Company's share of the tax basis of SSE Holdings due to redemptions or exchanges of LLC Interests, (ii) tax basis increases resulting from payments made under the Tax Receivable Agreement, and (iii) deductions from imputed interest under the agreement (the "TRA Payments"). The Company expects to benefit from the remaining 15% of any realized tax benefits. The TRA Payments are not conditioned upon any continued ownership interest in SSE Holdings or us. Additionally, the rights of each non-controlling interest holder under the Tax Receivable Agreement, are assignable to transferees of its 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 thirty-nine weeks ended September 30, 2026 and September 24, 2025.

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

NOTE 11: EARNINGS PER SHARE

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

20 |Shake Shack Inc. Form 10-Q

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

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 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 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 per share, except when the effect would be anti-dilutive.

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

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

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

NOTE 12: SUPPLEMENTAL CASH FLOW INFORMATION

The following table sets forth supplemental cash flow information:

NOTE 13: COMMITMENTS AND CONTINGENCIES

Lease Commitments

The Company is obligated under various operating leases for Shacks and Shack Support Centers expiring in various years through 2045.

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
