Shake Shack Announces Third Quarter 2020 Financial Results

–Average Weekly Sales and Same-Shack Sales Show Significant Sequential Improvement in both Urban and Suburban Shacks

–Sales in Company-Owned Digital Channels Tripled Compared to Prior Year

–Shack-level Operating Profit Improves to 14.8% Compared to 2.2% in Second Quarter 2020

NEW YORK, NY (Business Wire) — October 29, 2020 — Shake Shack Inc. (“Shake Shack” or the “Company”) (NYSE: SHAK) today reported its financial results for the third quarter ended September 23, 2020, a period that included 13 weeks.

Randy Garutti, Chief Executive Officer of Shake Shack, stated, “Our business during this most recent quarter showed steady recovery, thanks to the hard work and dedication of our team, their agility in adapting new Shack protocols and models and an increasingly strong suite of digital capabilities. As a result, guests have been able to enjoy their Shack the way they want it, with a choice of convenient and safe ordering and pick-up options, as we continue to expand and elevate the Shake Shack experience."

Garutti concluded, “Since our last update at the end of July, forward momentum has continued and we're encouraged to see significant improvement in both sales and profitability, with many Shacks returning to or exceeding last year's results. Total year-over-year company-operated Shack sales declined 17% in the third quarter, compared to a decline of 39% during the second quarter, and further improved to a decline of just 5% in fiscal October. Same-Shack sales have also improved sequentially in every single one of the last six months, with the third quarter down 31.7% compared to the same period last year, versus down 49.0% in the second quarter, and improving to down 21% in fiscal October. Importantly, our improving top line performance, the normalization of beef costs, and disciplined expense management led to a significant recovery in Shack-level profitability with third quarter Shack-level operating profit margin improving to 14.8%, compared to 2.2% in the second quarter. We believe we are uniquely positioned to exit this challenging period stronger, and with greater opportunity than when we entered, as we double down on multi-format expansion and accelerate our strategic digital investments. As of the end of fiscal October, we are back to a full development schedule, having opened 33 Shacks so far in this challenging year, including 15 domestic company-operated Shacks, and expect to complete the year with 18 to 20 total new company-operated Shacks. Our pipeline for 2021 is strong, and we expect to open between 35 and 40 new company-operated Shacks, many of which will incorporate our new Shack Track and Drive Thru designs centered on the hospitality and experience Shake Shack has been known for, with an added focus on speed, convenience and the integration of our pre-ordering digital capabilities.”

Third Quarter 2020 Review

Total revenue, which includes Shack sales and licensing revenue, decreased 17.3% versus the third quarter 2019, to $130.4 million in the third quarter of 2020, due to lost sales related to the impact from the COVID-19 pandemic. Total revenue has, however, shown steady and significant improvement when compared to a decline of 39.9% during the second quarter. Further improvement carried through fiscal October, with a year-over-year decline of 5.7%. Shack sales for the third quarter of 2020 were $126.3 million compared to $152.4 million in the third quarter 2019, a decrease of $26.1 million, or 17.1%, primarily due to a decline in same-Shack sales, partially offset by the opening of 24 new domestic company-operated Shacks between September 25, 2019 and September 23, 2020. Shack sales have also, notably improved from a decline of 39.5% during the second quarter, and also subsequent to the third quarter with fiscal October declining just 5.3% year-over-year.

Same-Shack sales improved across all regions on a sequential basis, with performance driven by increases in in-Shack dining in both urban and suburban Shacks, combined with high levels of retention of digital sales since fiscal May. Most notably, same-Shack sales have improved sequentially over each of the last six months. During the third quarter of 2020, same-Shack sales were down 31.7% compared to the same period last year, with the Company's urban Shacks down 43% and suburban Shacks down 16% compared to the same period last year. The decrease in same-Shack sales for the quarter was driven by a 42.0% decrease in traffic partially offset by an increase in price mix of 10.3%. This increase in price mix was driven by a significant increase in average check, primarily from a higher digital sales mix combined with an overall increase in check, due to higher items per order since the start of the pandemic. The Company's third quarter 2020 same-Shack sales reflect sequential improvement from the prior quarter, in which same-Shack sales were down 49.0%, with urban Shacks down 57% and suburban Shacks down 38%. Subsequent to the third quarter of 2020, in fiscal October 2020, same-Shack sales were down 21%, with the Company's urban Shacks down 33% and suburban Shacks down 4% compared to the same period last year. Urban Shacks represent approximately half the Shacks in the comparable base, yet accounted for approximately 60% of its same-Shack sales prior to the COVID-19 outbreak. As expected, urban locations are still acutely impacted by the pandemic and suburban locations continue to recover at a faster pace. New York City, particularly Manhattan, continues to lag other regions and the Company expects this to be an ongoing trend until the city fully recovers. New York City same-Shack sales have however, shown continued sequential improvement, being down 49% in the third quarter 2020 compared to down 64% in the second quarter, and now down 40% in fiscal October, versus the same periods last year. Manhattan will continue to have a material and outweighed impact on New York City’s results and those of the Company overall, with Manhattan still down 60% in same-Shack sales during the third quarter 2020, versus down 69% in the second quarter, and now down 51% in fiscal October.

Nearly all domestic company-operated Shacks were open as of the end of the third quarter 2020 and through fiscal October. As of the end of fiscal October, approximately 80% of the Company's domestic company-operated Shacks had open dining rooms with varying capacity restrictions, with the majority of Shacks also utilizing outdoor patio space, whenever possible.

During the third quarter of 2020, total digital sales, including orders placed on the Shake Shack app, website and third party delivery platforms, represented 60% of total Shack sales. As in-Shack sales improved throughout the period, the Company also maintained a high level of digital retention, with more than 90% of digital sales retained in fiscal October compared to the high point in fiscal May. During the third quarter and similar to second quarter trends, Shake Shack's native web and app channels, when combined, continued to be the fastest growing channel on a year-on-year basis, with sales more than three times the prior year levels. In the second quarter 2020, the Company added over 800,000 first-time purchasers to the app and web channels between early March and the end of July. This trend has continued through fiscal October, increasing to over 1.4 million first-time purchasers on those channels since early March.

The following table presents fiscal monthly information about the Company's current trends in Shack sales.

First <br>Quarter Second <br>Quarter Third <br>Quarter Fourth <br>Quarter
(dollar amounts in thousands) March 25 April 22 May 20 June 24 July 22 August 19 September 23 October 21
Average weekly sales $ 56 $ 32 $ 50 $ 52 $ 56 $ 59 $ 61 $ 62
Total year-over-year sales growth (decline) (11) % (56) % (32) % (32) % (23) % (20) % (10) % (5) %
Same-Shack sales % (29) % (64) % (42) % (42) % (39) % (34) % (23) % (21) %

Licensing revenue for the third quarter of 2020 was $4.1 million, a decrease of 23.8% from $5.4 million in the third quarter 2019, due to reduced sales related to the COVID-19 pandemic, partially offset by a net increase of 20 Shacks opening between September 25, 2019 and September 23, 2020. The Company's licensed business has shown gradual improvement, as noted in the table below. The Company's licensed airport and stadium business, however, continues to be deeply impacted, with only nine of the 22 domestic licensed Shacks open as of the end of fiscal October. The following table presents fiscal monthly information about the Company's licensed sales trends.

First Quarter Second <br>Quarter Third <br>Quarter Fourth <br>Quarter
(dollar amounts in millions) March 25 April 22 May 20 June 24 July 22 August 19 September 23 October 21
Weekly licensed sales(1) $ 4.6 $ 2.0 $ 2.4 $ 3.5 $ 4.6 $ 5.4 $ 5.7 $ 5.9
Total year-over-year licensed sales growth (decline) 13 % (65) % (58) % (47) % (32) % (23) % (9) % (10) %
Number of open licensed Shacks 96 56 59 91 98 104 105 107

(1)    Weekly licensed sales is an operating measure and consists of sales from domestic licensed Shacks and international licensed Shacks. The Company does not recognize the sales from licensed Shacks as revenue. Of these amounts, revenue is limited to licensing revenue based on a percentage of sales from domestic and international licensed Shacks, as well as certain up-front fees such as territory fees and opening fees.

During the third quarter of 2020, the Company opened four new domestic company-operated Shacks, five new international licensed Shacks, and one domestic licensed Shack. These openings were partially offset by the COVID-related closure of three international licensed Shacks and one domestic licensed Shack, including the Shack located in Terminal 3 of the LAX airport.

Operating loss for the third quarter of 2020 was $6.8 million, a negative operating margin of 5.2%, compared to operating income of $8.2 million, or an operating margin of 5.2% for the third quarter 2019. For the third quarter of 2020, Shack-level operating profit, a non-GAAP measure, was $18.7 million, or 14.8% as a percentage of Shack sales, compared to Shack-level operating profit of $1.9 million, or 2.2% of Shack sales in the second quarter 2020. Shack-level operating profit performance improved sequentially throughout the third quarter, with fiscal July margin of 12%, fiscal August margin of 14% and the five-week fiscal September margin of 17%. The year-over-year decrease in Shack-level operating profit was primarily due to sales deleverage resulting from the impact of COVID-19. In addition this decrease was also driven by increased paper and packaging costs as a result of packaging all orders as 'to go' orders, a number of incremental payroll costs to support Shack employees and higher delivery commissions as a result of digital growth. A reconciliation of Shack-level operating profit to operating income (loss), 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 decreased to $15.0 million for the third quarter of 2020 from $17.1 million in the third quarter 2019. This was primarily due to disciplined cost reduction across the majority of discretionary spend categories and reduced home office compensation expense, partially offset by increased expenses across marketing and technology to support digital initiatives. As a percentage of total revenue, general and administrative expenses increased to 11.5% for the third quarter of 2020 from 10.8% in the third quarter 2019, primarily due to sales deleverage associated with the impact of COVID-19.

Net loss for the third quarter of 2020 was $6.1 million, or 4.7% of total revenue, compared to net income of $11.4 million, or 7.2% of total revenue, for the third quarter 2019. Net loss attributable to Shake Shack Inc. for the third quarter of 2020 was $5.6 million, or 4.3% of total revenue, compared to net income attributable to Shake Shack Inc. of $10.3 million, or 6.6% of total revenue, for the third quarter 2019. Loss per diluted share for the third quarter of 2020 was $0.15 compared to earnings per diluted share of $0.31 for the third quarter 2019.

Updated 2020 Outlook

Given the substantial uncertainty and resulting material economic impact caused by the COVID-19 pandemic, the Company is not providing full guidance for the fiscal year ending December 30, 2020. While the Company is confident in a full, long term recovery, the timing of that return to pre-COVID levels is highly dependent upon the return of the high traffic areas that contributed to many of the strongest Shack sales, including those most reliant on travel, schools, offices and major gatherings, as well as ultimately, fully open dining rooms. The timing of that recovery remains unknown today. With the colder weather and the increasing number of reported COVID cases, it is expected that sales over the coming months will be pressured. The Company has the benefit of a 53rd week in this fiscal year which will be accretive on an absolute dollar basis, but the underlying business continues to face a very challenging and volatile operating environment certainly through the end of this year.

The Company expects to reach a total of 18 to 20 new company-operated Shacks by the end of fiscal 2020. Furthermore, the Company expects to open five to six new licensed Shacks in the fourth quarter 2020, ending the year with 12 to 14, net licensed Shacks in total for fiscal 2020. Looking to the next fiscal year, the Company expects to open between 35 and 40 new company-operated Shacks in fiscal 2021, a number of which should open in the first half of fiscal 2021. Additionally, the Company expects to open 15 to 20 new licensed Shacks in fiscal 2021.

With the continued recovery of Shack-level operating profit highly correlated to sales performance in terms of leverage on fixed costs, combined with the continuation of certain elevated costs specific to the pandemic, the Company expects any ongoing improvement in Shack-level operating margin in the fourth quarter to face pressure.

The Company expects fourth quarter 2020 general and administrative expenses to approach the same level of spend as the fourth quarter 2019.

Pre-opening expense for the third quarter 2020 was $1.8 million, however, now that development is back to a full opening schedule, this spend will increase meaningfully, and is expected to more than double sequentially through the fourth quarter 2020 as the Company completes this year's opening schedule.

Excluding the tax impact of stock based compensation, the adjusted pro forma tax rate in the third quarter 2020 was 29.3%, slightly higher than guidance given earlier in the year. The year-to-date adjusted pro forma tax rate was 28.1%, and is in line with full fiscal year expectations at this time. A reconciliation of the Company's tax rates is included in the appendix of our supplemental materials.

Definitions

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

"Shack sales" is defined as the aggregate sales of food, beverages and Shake Shack branded merchandise at 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. For days that Shacks were temporarily closed, the comparative 2019 period was also adjusted.

"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.

"Weekly licensed sales” is calculated by dividing the total sales for the period for all licensed Shacks by the number of weeks in the period.

"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 (loss) before interest expense (net of interest income), income tax expense (benefit), and depreciation and amortization expense.

“Adjusted EBITDA,” a non-GAAP measure, is defined as EBITDA (as defined above), excluding equity-based compensation expense, deferred lease costs, impairment and loss on disposal of assets, amortization of cloud-based software implementation costs, as well as certain non-recurring items that the Company does not believe directly reflect its core operations and may not be indicative of the Company's recurring business operations.

“Adjusted EBITDA margin,” a non-GAAP measure, is defined as net income (loss) before net interest, taxes, depreciation and amortization, which also excludes equity-based compensation expense, deferred lease costs, impairment and loss on disposal of assets, amortization of cloud-based software implementation costs, as well as certain non-recurring and other items that the Company does not believe directly reflect its core operations, as a percentage of revenue.

"Adjusted pro forma net income (loss)," 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 and other items that the Company does not believe directly reflect its core operations.

See “Non-GAAP Financial Measures.”

SHAKE SHACK INC.

NON-GAAP FINANCIAL MEASURES

(UNAUDITED)

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 (loss) and adjusted pro forma earnings (loss) 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 (loss), the most directly comparable GAAP financial measure, is set forth below.

NON-GAAP FINANCIAL MEASURES

(UNAUDITED)

EBITDA and Adjusted EBITDA

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

How These Measures Are Useful

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

Limitations of the Usefulness of These Measures

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

(4)    Represents fees paid in connection with the search and hiring of certain executive and key management positions.

(5)    Represents consulting and advisory fees related to the Company's enterprise-wide system upgrade initiative called Project Concrete.

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 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 (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 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 (loss) 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 (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 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 (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 GAAP financial results. A reconciliation of adjusted pro forma net income (loss) to net income (loss) attributable to Shake Shack Inc., the most directly comparable GAAP measure, and the computation of adjusted pro forma earnings (loss) per fully exchanged and diluted share are set forth below.
