Fourth Quarter 2018 Review

Total revenue, which includes Shack sales and licensing revenue, increased 29.3% to $124.3 million in the fourth quarter of 2018 from $96.1 million for the fourth quarter of 2017. Shack sales for the fourth quarter of 2018 were $120.7 million, an increase of 29.6% from $93.1 million in the same quarter last year due primarily to the opening of 34 new domestic company-operated Shacks between the fourth quarter of 2018 and the fourth quarter of 2017, as well as same-Shack sales growth. Licensing revenue for the fourth quarter was $3.5 million, an increase of 17.9% from $3.0 million in the same quarter last year, primarily due to the opening of 15 net new licensed Shacks between the fourth quarter of 2018 and the fourth quarter of 2017 and the initial strength of newer Shacks in Hong Kong and Japan.

Same-Shack sales increased 2.3% for the fourth quarter of 2018 versus 0.8% growth in the fourth quarter last year, which was primarily driven by a combined increase of 2.6% in price and sales mix partially offset by decreased guest traffic of 0.3%. The comparable Shack base includes those restaurants open for 24 full fiscal months or longer. At the end of the fourth quarter of 2018, the comparable Shack base included 61 Shacks versus 43 Shacks for the fourth quarter of 2017.

Average weekly sales for domestic company-operated Shacks decreased to $81,000 for the fourth quarter of 2018 compared to $85,000 for the same quarter last year, primarily due to the addition of newer Shacks at a broader range of average unit volumes.

Operating income decreased to $2.8 million for the fourth quarter of 2018 from $5.8 million in the same quarter last year. As a percentage of revenue, operating income margins decreased 380 basis points to 2.3%. These decreases were primarily due to higher pre-opening costs from a 55% increase in the number of openings, $0.7 million of one-time costs related to Project Concrete, the Company's enterprise-wide system upgrade initiative, and various factors impacting Shack-level operating profit. Shack-level operating profit, a non-GAAP measure, increased 15.6% to $27.2 million for the fourth quarter of 2018 from $23.5 million in the same quarter last year. As a percentage of Shack sales, Shack-level operating profit margins decreased 270 basis points to 22.5% primarily due to (i) increased labor and related expenses resulting from ongoing increases in minimum wages, regulatory factors, such as the Fair Workweek legislation in New York City, and the opening of 17 new domestic company-operated Shacks during the quarter, which typically carry higher labor costs during the first few months of operations; (ii) commissions paid as part of integrated delivery pilots during the quarter, for which no costs were incurred in the same quarter last year; and (iii) the addition of new Shacks at a broader range of average unit volumes. These were partially offset by a decrease in rent expense due to an increase in the number of leases where the Company is deemed to be the accounting owner and for which less rent expense is recognized. A reconciliation of operating income to Shack-level operating profit, the most directly comparable GAAP financial measure, is set forth in the schedules accompanying this release. See “Non-GAAP Financial Measures.”

General and administrative expenses increased 30.2% to $15.2 million for the fourth quarter of 2018 from $11.7 million in the same quarter last year, primarily due to the increase in the Company's investment across the business, particularly in digital, people resources and foundational infrastructure to support its ongoing growth initiatives, including costs of $0.7 million related to Project Concrete and other one-time charges. As a percentage of total revenue, general and administrative expenses increased to 12.2% for the fourth quarter of 2018 from 12.1% in the fourth quarter last year, primarily due to the aforementioned items.

Net loss was $0.5 million for the fourth quarter of 2018 compared to a loss of $11.0 million for the same period last year. Net loss attributable to Shake Shack Inc. was $1.0 million, or $0.03 per diluted share, for the fourth quarter of 2018, compared to a loss of $12.5 million, or $0.47 per diluted share, for the same period last year. This increase was primarily due to the Tax Cuts and Jobs Act of 2017 (the "TCJA") that was enacted into law in December 2017, which resulted in an additional $138.6 million of income tax expense and a related benefit of $125.9 million related to the remeasurement of the Company's deferred tax assets and liabilities under its tax receivable agreement. There were no such adjustments in the current year.

Adjusted EBITDA, a non-GAAP measure, decreased 3.2% to $14.5 million. As a percentage of total revenue, adjusted EBITDA margins decreased approximately 390 basis points to 11.6% compared to 15.5% for the prior year period. These decreases were primarily due to the aforementioned items within Shack-level operating profit. A reconciliation of net income (loss) to adjusted EBITDA, the most directly comparable GAAP financial measure, is set forth in the schedules accompanying this release. See “Non-GAAP Financial Measures.”

Adjusted pro forma net income, a non-GAAP measure, was $2.4 million, or $0.06 per fully exchanged and diluted share during the fourth quarter of 2018, compared to $3.9 million, or $0.10 per diluted share during the fourth quarter of 2017. These decreases were primarily due to the aforementioned items within operating income and Shack-level operating profit. A reconciliation of net income (loss) attributable to Shake Shack Inc. to adjusted pro forma net income is set forth in the schedules accompanying this release. See “Non-GAAP Financial Measures.”

Fiscal Year 2018 Review

Total revenue,which includes Shack sales and licensing revenue, increased 28.0% to $459.3 million for fiscal 2018 from $358.8 million for fiscal 2017. Shack sales for fiscal 2018 were $445.6 million, an increase of 28.6% from fiscal 2017 due primarily to the opening of 34 new domestic company-operated Shacks during fiscal 2018, as well as same-Shack sales growth. Licensing revenue for fiscal 2018 was $13.7 million, an increase of 10.5% from $12.4 million for fiscal 2017, primarily due to the opening of 15 net new licensed Shacks during fiscal 2018 and strong performance in Asia, including the initial strength of newer Shacks in Hong Kong and Japan.

Same-Shack sales increased 1.0% for fiscal 2018 versus a 1.2% decline in the prior year, which was primarily driven by a combined increase of 3.7% in price and sales mix partially offset by decreased guest traffic of 2.7%. At the end of fiscal 2018, the comparable Shack base included 61 Shacks, compared to 43 Shacks for fiscal 2017.

Average unit volume for domestic company-operated Shacks was $4.4 million for 2018 compared to $4.6 million for the prior year, a 4.5% decrease, primarily due to the addition of newer Shacks at lower average unit volumes.

Operating income decreased to $31.7 million for fiscal 2018 from $33.8 million for fiscal 2017 and operating income margins decreased 250 basis points to 6.9% , which included $3.9 million of one-time charges, comprised of a legal settlement of $1.2 million and costs related to Project Concrete. Shack-level operating profit, a non-GAAP measure, increased 22.3% to $112.9 million for fiscal 2018 from $92.3 million for fiscal 2017. As a percentage of Shack sales, Shack-level operating profit margins decreased approximately 130 basis points to 25.3% primarily due to (i) increased labor and related expenses resulting from ongoing increases in minimum wages, regulatory factors, such as the Fair Workweek legislation in New York City, and the opening of 34 new domestic company-operated Shacks during fiscal 2018, which typically carry higher labor costs during the first few months of operations; (ii) commissions paid as part of integrated delivery pilots, for which no costs were incurred in the same quarter last year; (iii) higher repair and maintenance costs related to some mature, high-volume Shacks; and (iv) the addition of new Shacks at a broader range of average unit volumes. These were partially offset by a decrease in rent expense due to an increase in the number of leases where the Company is deemed to be the accounting owner and for which less rent expense is recognized. A reconciliation of operating income to Shack-level operating profit, the most directly comparable GAAP financial measure, is set forth in the schedules accompanying this release. See “Non-GAAP Financial Measures.”

General and administrative expenses increased to $52.7 million for fiscal 2018 from $39.0 million for fiscal 2017, primarily due to the increase in the Company's investment across the business, particularly the addition of headcount to support its ongoing growth initiatives and $3.9 million of one-time charges, including a legal settlement of $1.2 million and costs related to Project Concrete. As a percentage of total revenue, general and administrative expenses increased to 11.5% for fiscal 2018 from 10.9% in fiscal 2017, primarily due to the aforementioned items. Excluding the costs associated with Project Concrete and other one-time charges, general and administrative expenses as a percentage of revenue would have decreased to 10.6% for fiscal 2018.

Net income was $21.9 million for fiscal 2018 compared to income of $8.9 million for fiscal 2017. Net income attributable to Shake Shack Inc. was $15.2 million, or $0.52 per diluted share, for fiscal 2018, compared to a loss of $0.3 million, or $0.01 per diluted share, for fiscal 2017. This increase was primarily due to he Tax Cuts and Jobs Act of 2017 (the "TCJA") that was enacted into law in December 2017, which resulted in an additional $138.6 million of income tax expense and a related benefit of $125.9 million related to the remeasurement of the Company's deferred tax assets and liabilities under its tax receivable agreement. There were no such adjustments in the current year.

Adjusted EBITDA, a non-GAAP measure, increased 14.2% to $73.9 million from $64.7 million for the fiscal year. As a percentage of total revenue, adjusted EBITDA decreased roughly 190 basis points to 16.1% compared to 18.0% for the year ago period. This decrease was primarily due to the aforementioned items within Shack-level operating profit. A reconciliation of net income (loss) to adjusted EBITDA, the most directly comparable GAAP financial measure, is set forth in the schedules accompanying this release. See “Non-GAAP Financial Measures.”

Adjusted pro forma net income, a non-GAAP measure, was $26.9 million, or $0.71 per fully exchanged and diluted share for fiscal 2018, compared to $21.0 million, or $0.57 per fully exchanged and diluted share for fiscal 2017. A reconciliation of net income (loss) attributable to Shake Shack Inc. to adjusted pro forma net income is set forth in the schedules accompanying this release. See “Non-GAAP Financial Measures.”

Definitions

The following definitions apply to these terms as used in this release:

"Shack sales" is defined as the aggregate sales of food and beverages in domestic company-operated Shacks and excludes sales from licensed Shacks.

"Same-Shack sales" represents Shack sales for the comparable Shack base, which is defined as the number of domestic company-operated Shacks open for 24 full fiscal months or longer.

"Average unit volume" or "AUV" for any 12-month period consist of the average annualized sales of all domestic company-operated Shacks over that period. AUV is calculated by dividing total Shack sales from domestic company-operated Shacks by the number of domestic company-operated Shacks open during that period. For Shacks that are not open for the entire period, fractional adjustments are made to the number of Shacks open such that it corresponds to the period of associated sales. The measurement of AUV allows the Company to assess changes in guest traffic and per transaction patterns at domestic company-operated Shacks.

"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.

"Shack-level operating profit," a non-GAAP measure, is defined as Shack sales less Shack-level operating expenses including food and paper costs, labor and related expenses, other operating expenses and occupancy and related expenses.

"Shack-level operating profit margin," a non-GAAP measure, is defined as Shack sales less Shack-level operating expenses including food and paper costs, labor and related expenses, other operating expenses and occupancy and related expenses as a percentage of Shack sales.

“EBITDA,” a non-GAAP measure, is defined as net income before net interest, taxes, depreciation and amortization.

“Adjusted EBITDA,” a non-GAAP measure, is defined as net income before net interest, taxes, depreciation and amortization, which also excludes equity-based compensation expense, deferred rent expense, losses on the disposal of property and equipment, as well as certain non-recurring items that the Company does not believe directly reflect its core operations.

“Adjusted EBITDA margin,” a non-GAAP measure, is defined as net income before net interest, taxes, depreciation and amortization, which also excludes equity-based compensation expense, deferred rent expense, losses on the disposal of property and equipment, as well as certain non-recurring items that the Company does not believe directly reflect its core operations, as a percentage of revenue.

"Adjusted pro forma net income," a non-GAAP measure, 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 the Company does not believe directly reflect its core operations.

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

Shack-Level Operating Profit

Shack-level operating profit is defined as Shack sales less Shack-level operating expenses including food and paper costs, labor and related expenses, other operating expenses and occupancy and related expenses.

How This Measure Is Useful

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

Limitations of the Usefulness of this Measure

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

EBITDA and Adjusted EBITDA

EBITDA is defined as net income 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, deferred rent expense, losses on the disposal of property and equipment, as well as certain non-recurring items that the Company does not believe directly reflect its core operations and may not be indicative of the Company's recurring business operations.

How These Measures Are Useful

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

Limitations of the Usefulness of These Measures

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

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

Adjusted pro forma net income represents net income (loss) attributable to Shake Shack Inc. assuming the full exchange of all outstanding SSE Holdings, LLC membership interests ("LLC Interests") for shares of Class A common stock, adjusted for certain non-recurring items that the Company does not believe are directly related to its core operations and may not be indicative of recurring business operations. Adjusted pro forma earnings per fully exchanged and diluted share is calculated by dividing adjusted pro forma net income by the weighted-average shares of Class A common stock outstanding, assuming the full exchange of all outstanding LLC Interests, after giving effect to the dilutive effect of outstanding equity-based awards.

How These Measures Are Useful

When used in conjunction with GAAP financial measures, adjusted pro forma net income and adjusted pro forma earnings per fully exchanged and diluted share are supplemental measures of operating performance that the Company believes are useful measures to evaluate performance period over period and relative to its competitors. By assuming the full exchange of all outstanding LLC Interests, the Company believes 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 attributable to Shake Shack Inc. driven by increases in its ownership of SSE Holdings, which are unrelated to the Company's operating performance, and excludes items that are non-recurring or may not be indicative of ongoing operating performance.

Limitations of the Usefulness of These Measures

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