Shake Shack is a modern day "roadside" burger stand serving a classic American menu of premium burgers, chicken sandwiches, hot dogs, crinkle cut fries, shakes, frozen custard, beer and wine.

As of September 23, 2020, there were 298 Shacks in operation system-wide, of which 175 were domestic Company-operated Shacks, 22 were domestic licensed Shacks and 101 were international licensed Shacks.

Recent Developments and Trends

We have experienced steady recovery in the business during the third quarter of 2020, and through October 21 ("fiscal October"), all while continuing to support our Shack teams, our guests and the communities in which we operate during the COVID-19 global pandemic.

COVID-19 was officially declared a global pandemic by the World Health Organization in March 2020, and the virus has impacted all global economies, resulting in varying levels of restrictions and shutdowns implemented by national, state, and local authorities.

In response to the outbreak, in March 2020, we closed all dining rooms and temporarily shifted to a “to-go” only operating model in all of our domestic Company-operated Shacks.

With a prioritization on health and safety, we have steadily re-opened Shacks under modified operations to meet public health guidelines and evolving customer behaviors and expectations.

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 our domestic Company-operated Shacks had open dining rooms with varying capacity restrictions, with the majority of Shacks also utilizing outdoor patio space, whenever possible.

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 every single one 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 urban Shacks down 43% and suburban Shacks down 16% compared to the same period last year.

Our third quarter 2020 same-Shack sales reflect sequential improvement against 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 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 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

As of March 31, 2021, there were 321 Shacks in operation system-wide, of which 192 were domestic Company-operated Shacks, 22 were domestic licensed Shacks and 107 were international licensed Shacks.

recover at a faster pace.

New York City, particularly Manhattan, continues to lag other regions and we expect 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.

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, we 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, our 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, we 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 our current trends in Shack sales.

*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.

Our licensed business has shown gradual improvement.

Our 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 our licensed sales trends.

* Weekly licensed sales is an operating measure and consists of sales from domestic licensed Shacks and international licensed Shacks.

We do 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.

Given the substantial uncertainty and resulting material economic impact caused by the COVID-19 pandemic, we are not providing full guidance for the fiscal year ending December 30, 2020.

While we are 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.

We have 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 yea r.

Recent Developments and Trends

We have experienced continued positive momentum in the business during the first quarter of 2021, and through April 28 ("fiscal April"), all while continuing to support our Shack teams, our guests and the communities in which we operate during the COVID-19 pandemic.

With COVID cases stabilizing and more regions steadily loosening restrictions, we are optimistic that improving trends can continue for our industry.

With a continued prioritization on health and safety, we have steadily re-opened dining rooms under modified operations to meet public health guidelines and evolving customer behaviors and expectations.

Same-Shack sales continued to improve across all regions, up 5.7% in the first quarter 2021, when compared to down 17.4% in the fourth quarter 2020, with performance driven by increases in in-Shack dining in both urban and suburban Shacks, combined with high levels of digital sales retention.

Same-Shack sales in fiscal April were up 86% compared to the same period last year.

As of the end of fiscal April 2021, the vast majority of Shacks were operating with open dining rooms, the majority of which continue to remain under varying levels of capacity restrictions, especially in urban Shacks.

The Company continues to experience recovery across urban and suburban markets, however many major urban markets, such as Manhattan, remain materially below pre-COVID levels, while office, events and tourism traffic return.

Average weekly sales were $64,000 in the first quarter of 2021.

Fiscal February was heavily impacted by severe winter weather, resulting in average weekly sales of $60,000, followed by a significant improvement to $68,000 in fiscal March, and continuing through fiscal April with $69,000.

This continued improvement was driven by a substantial increase in in-Shack sales, as well as a high retention of digital sales.

During the first quarter of 2021, total digital sales, including orders placed on the Shake Shack app, website and third-party delivery platforms, represented 60% of Shack sales.

Fiscal January and February digital mix was 64% and 62% of Shack sales, respectively, driven largely by increased delivery due to bad weather across large portions of the United States.

Digital sales mix decreased to 54% of Shack sales in fiscal March and 51% of Shack sales in fiscal April, driven by an increase in in-Shack dining as the weather improved and parts of the country continued to re-open.

Encouragingly, while in-Shack dining continues to increase, there continues to be a high level of digital sales retention with 90% of fiscal January's digital sales retained in fiscal April.

Company-owned app and web channels continued to perform well in the first quarter 2021, with 2.4 million first-time purchasers between mid-March of 2020 and the end of fiscal March 2021, and over 230% year-over-year sales growth, when compared to the first quarter 2020.

Licensing revenue for the first quarter of 2021 was $4.6 million, reflecting a decrease of 9.9% versus the same period last year.

We did, however, see improvement in total weekly sales performance throughout the quarter, with sales recovery led by improvements in both our international and domestic licensed Shacks, particularly in airports which are experiencing increases in Transportation Security Administration ("TSA") flight traffic.

Development Highlights

During the third quarter 2020, we 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.

During the first quarter 2021, we opened ten new domestic Company-operated Shacks and two new international licensed Shacks.

These openings were partially offset by the closure of one domestic Company-operated Shack and one international licensed Shack.

Liquidity Update

In March 2020, we drew down the full $50.0 million available under the Revolving Credit Facility, of which the full amount was repaid, plus interest, in fiscal June 2020.

In fiscal April 2020, we raised $135.9 million of proceeds, net of underwriting discounts and commissions, from the sale of 3,416,070 shares of its Class A common stock in an underwritten offering, and $9.8 million of proceeds, net of commissions, from the sale of 233,467 shares of its Class A common stock pursuant to an "at-the-market" equity offering program.

See “Liquidity and Capital Resources,” herein, for more information.

In March 2021, we issued $225 million aggregate principal amount of 0% Convertible Senior Notes due 2028 (the “Convertible Notes”) in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933.

We granted an option to the initial purchasers to purchase up to an additional $25 million aggregate principal amount of Convertible Notes to cover over-allotments, which was subsequently fully exercised during March 2021, resulting in a total issuance of $250 million aggregate principal amount of Convertible Notes.

The Convertible Notes will mature on March 1, 2028, unless earlier converted, redeemed or repurchased in certain circumstances.

Upon conversion, we pay or deliver, as the case may be, cash, shares of Shake Shack’s Class A common stock or a combination of cash and shares of Shake Shack’s Class A common stock, at our election.

Table of Content

The decrease in Shack sales for the thirteen and thirty-nine weeks ended September 23, 2020 was primarily due to lost sales related to the impact from the COVID-19 pandemic.

These decreases were partially offset by the opening of 24 new domestic Company-operated Shacks between September 25, 2019 and September 23, 2020.

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 a high retention of digital sales from the high point since fiscal May.

Most notably, same-Shack sales have improved sequentially over each of the last six months.

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.

For the thirty-nine weeks ended September 23, 2020, same-Shack sales were down 31.5%, primarily driven by a 39.4% decrease in guest traffic partially offset by an increase in price mix of 7.9%, also driven by a higher total average check.

For the purpose of calculating same-Shack sales growth for the thirteen and thirty-nine weeks ended September 23, 2020, Shack sales for 102 Shacks were included in the comparable Shack base.

Subsequent to the third quarter of 2020, in fiscal October 2020, same-Shack sales were down 21%, with our urban Shacks down 33% and suburban Shacks down 4% compared to the same period last year.

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

Same-Shack sales continued to improve across all regions, and increased 5.7% for the first quarter of 2021, compared to down 17.4% in the fourth quarter of 2020, with performance driven by increases in in-Shack dining in both urban and suburban Shacks, combined with high levels of digital sales retention.

The increase in first quarter 2021 same-Shack sales was due to a price and sales mix increase of 18.0% — a combination of our end-of-year price increase in December, increased pricing on third-party delivery channels which rolled out over the early part of this fiscal year, and a higher number of items per check, particularly in our digital channels — partially offset by a 12.3% decrease in guest traffic.

For the purpose of calculating same-Shack sales growth, Shack sales for 123 Shacks were included in the comparable Shack base as of the end of the first quarter of 2021 versus 90 Shacks for the first quarter of 2020.

Percentage change compared to prior year (9.9) %

The decreases in licensing revenue for the thirteen and thirty-nine weeks ended September 23, 2020 were primarily due to reduced sales related to the COVID-19 pandemic, partially offset by a net increase of 20 Shacks opened between September 25, 2019 and September 23, 2020.

Our licensed business has shown improvement, with our licensed airport and stadium business continuing to be the most deeply impacted, with only nine of the 22 domestic licensed Shacks open as of fiscal October.

Licensed revenue for the thirteen weeks ended March 31, 2021 decreased 9.9% to $4.6 million versus the same prior-year period, primarily due to reduced sales related to the COVID-19 pandemic, partially offset by a net increase of 9 Shacks opened between March 25, 2020 and March 31, 2021.

As of the end of the first quarter 2021, 16 licensed Shacks remained temporarily closed due to COVID.

Through the first quarter of 2021, we did, however, see improvement in total weekly sales performance throughout the quarter, with sales recovery led by improvements in both our international and domestic licensed Shacks, particularly in airports which are experiencing increases in TSA flight traffic.

For the thirty-nine weeks ended September 23, 2020, as a percentage of Shack sales, the increase in food and paper costs was primarily due to higher paper and packaging costs and significant inflation in beef prices, partially offset by lower chicken costs.

For the large part of the second quarter of 2020, we experienced significant inflation in beef, with costs nearly double that of last year for most of June.

Beef prices have since returned to more normalized levels in the third quarter of 2020.

Furthermore, we had increased paper and packaging costs as a result of packaging all orders as 'to go' orders during the second and third quarter of 2020.

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

Percentage change compared to prior year 11.1 %

The decreases in labor and related expenses for the thirteen and thirty-nine weeks ended September 23, 2020 were primarily due to reductions in staffing expenses across all Shacks associated with the impact of COVID-19.

These decreases were partially offset by the opening of 24 new domestic Company-operated Shacks between September 25, 2019 and September 23, 2020, and a number of incremental payroll costs to support our Shack employees.

These incremental payroll costs were related to a temporary 10% premium pay raise to hourly employees through the end of August, guaranteed bonuses for Shack teams, and payments related to scheduling changes for hourly team members as teams navigated the challenging operating conditions caused by COVID-19.

This investment in our teams had an incremental $2.1 million impact on our results of operations during the third quarter of 2020, and was in addition to the $2.4 million recognized during the second quarter of 2020.

As a percentage of Shack sales, the increase in labor and related expenses for the thirteen and thirty-nine weeks ended September 23, 2020 was primarily due to sales deleverage associated with the impact of COVID-19 and, to a lesser extent, increases in starting wages, partially offset by the reduction of labor hours.

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 we believe are useful measures to evaluate the performance and profitability of our Shacks.

Additionally, Shack-level operating profit and Shack-level operating 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 employee compensation as it serves as a metric in certain of our performance-based employee bonus arrangements.

We believe presentation of Shack-level operating profit and Shack-level operating 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.

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

Adjusted pro forma net income 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 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, 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.

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 infrastructure.

In addition, we are obligated to make payments to certain members of SSE Holdings under the Tax Receivable Agreement.

As of September 23, 2020, such obligations totaled $228.2 million.

As of March 31, 2021, such obligations totaled $234.0 million.

Amounts payable under the Tax Receivable Agreement are contingent upon, among other things, (i) generation of future taxable income over the term of the Tax Receivable Agreement and (ii) future changes in tax laws.

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.

Operating Activities

For the thirty-nine weeks ended September 23, 2020 net cash provided by operating activities was $28.5 million compared to $73.0 million for the thirty-nine weeks ended September 25, 2019, a decrease of $44.5 million.

This decrease was primarily driven by a decrease in Shack-level operating profit due to the impact of COVID-19, partially offset by lower pre-opening costs.

For the thirteen weeks ended March 31, 2021 net cash provided by operating activities was $10.0 million compared to $7.5 million for the thirteen weeks ended March 25, 2020, an increase of $2.5 million.

The increase was primarily due to change in operating assets and liabilities of $3.9 million and an increase in net income of $1.7 million, partially offset by the impact of non-cash charges of $3.1 million.

The $3.9 million change in our operating asset and liability balances was primarily driven by Accrued wages and related liabilities being a source of cash of $2.9 million in the first quarter of 2021, primarily driven by higher accruals associated with payroll costs, compared to a use of cash of $5.1 million in the first quarter of 2020;

Accounts payable being a source of cash of $1.5 million in the first quarter of 2021, driven by timing of payments, compared to a use of cash of $4.4 million in the first quarter of 2020;

partially offset by Accrued expenses being a use of cash of $9.4 million in the first quarter of 2021, due to the timing of accruals associated with tax payments, compared to a use of cash of $6.3 million in the first quarter of 2020;

Other long-term liabilities being a use of cash of $1.8 million in the first quarter of 2021, due to the timing of tax payments, compared to a source of cash of $0.5 million in the first quarter of 2020;

and Accounts Receivable being a source of cash of $0.6 million in the first quarter of 2021, primarily driven by timing of cash receipts of open receivables, compared to a source of cash of $3.2 million in the first quarter of 2020.

Investing Activities

For the thirty-nine weeks ended September 23, 2020 net cash used in investing activities was $27.3 million compared to $54.9 million for the thirty-nine weeks ended September 25, 2019, a decrease of $27.6 million.

This decrease was primarily due to a decrease of $33.9 million in capital expenditures, as well as a decrease of $7.0 million of proceeds from sales of marketable securities.

For the thirteen weeks ended March 31, 2021 net cash used in investing activities was $27.2 million compared to net cash provided by investing activities of $0.6 million for the thirteen weeks ended March 25, 2020, a decrease of $27.8 million.

This decrease was primarily due to a decrease of $20.0 million of proceeds from sales of marketable securities, an increase of $4.0 million in capital expenditures to support our real estate development and digital initiatives and increased purchases of marketable securities of $3.9 million.

Financing Activities

For the thirty-nine weeks ended September 23, 2020 net cash provided by financing activities was $136.6 million compared to $1.6 million for the thirty-nine weeks ended September 25, 2019, an increase of $135.0 million.

This increase was primarily due to $145.0 million in net cash proceeds from the issuance of Class A common stock, partially offset by increased payments made under the Tax Receivable Agreement and distributions to our non-controlling interest holders.

For the thirteen weeks ended March 31, 2021 net cash provided by financing activities was $245.4 million compared to $42.6 million for the thirteen weeks ended March 25, 2020, an increase of $202.8 million.

This increase was primarily due to $243.8 million in net cash proceeds from the issuance of the Convertible Notes, decreased payments made under the Tax Receivable Agreement, and increased proceeds from stock option exercises, partially offset by $50.0 million in gross cash proceeds from the drawdown of funds from our Revolving Credit Facility in the first quarter of 2020 — which was repaid in full, plus interest, in the second quarter of 2020.

Revolving Credit Facility

In August 2019, we terminated our previous revolving credit facility and entered into a new Revolving Credit Facility agreement, which permits borrowings up to $50.0 million, of which the entire amount is available immediately, with the ability to increase available borrowings up to an additional $100.0 million, to be made available subject to satisfaction of certain conditions.

We repaid this amount in full, plus interest, in June 2020.

In May 2020, we entered into a First Amendment, which, among other things, provided for modified financial covenant compliance requirements for a period of time.

The First Amendment required us to maintain minimum liquidity of $25.0 million through July 1, 2021 and outstanding borrowings during the applicable period covered by the First Amendment bore interest at either:

(i) LIBOR plus a percentage ranging from 1.0% to 2.5% or (ii) the base rate plus a percentage ranging from 0.0% to 1.5%, in each case depending on our net lease adjusted leverage ratio.

To the extent the LIBOR reference rate is no longer available, the administrative agent, in consultation with us, will determine a replacement rate which will be generally in accordance with similar transactions in which it serves as administrative agent.

In March 2021, we entered into a Second Amendment.

The Second Amendment modified the applicable covenants and restrictions in the Credit Agreement to permit the incurrence of the Convertible Notes (as defined below), including obligations and transactions in connection therewith.

In addition, the Second Amendment, among other things, (i) extended the period applicable to the increased interest rate margin as set forth in the First Amendment;

(ii) shortened the maturity date of the Revolving Credit Facility from August 2024 to September 2022 and (iii) added mechanics relating to the transition from the use of LIBOR to SOFR upon the discontinuance or unavailability of LIBOR.

Subsequently, and also in March 2021, we entered into a Third Amendment with JPMorgan Chase Bank, N.A.

(as successor agent to Wells Fargo Bank, National Association), as administrative agent, and the lenders party thereto.

In addition, in March 2021, Wells Fargo Bank resigned as administrative agent under the Revolving Credit Facility and assigned its commitments thereunder to JPMorgan Bank, N.A.

The Third Amendment appoints JPMorgan Bank, N.A.

as administrative agent under the Revolving Credit Facility.

In addition, the Third Amendment, among other things, extends the maturity date of the Revolving Credit Facility from September 2022 to March 2026.

As of March 31, 2021 and December 30, 2020, no amounts were outstanding under the Revolving Credit Facility.

The obligations under the Revolving Credit Facility are secured by a first-priority security interest in substantially all of the assets of SSE Holdings and the guarantors.

Total interest expense for the thirteen weeks ended March 31, 2021 primarily included write-off of previously capitalized costs on the Revolving Credit Facility.

Convertible Notes

In March 2021, we issued $225.0 million aggregate principal amount of 0% Convertible Senior Notes due 2028 in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933.

We granted an option to the initial purchasers to purchase up to an additional $25.0 million aggregate principal amount of Convertible Notes to cover over-allotments, which was subsequently fully exercised during March 2021, resulting in a total issuance of $250.0 million aggregate principal amount of Convertible Notes.

The Convertible Notes will mature on March 1, 2028, unless earlier converted, redeemed or repurchased in certain circumstances.

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:

consecutive trading days ending on, and including, the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price for the Convertible Notes on each applicable trading day;

(2) during the five business day period after any ten consecutive trading day period in which the trading price (as defined in the Indenture) per $1,000 principal amount of the Convertible Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of Class A common stock and the conversion rate for the Convertible Notes on each such trading day;

(3) if we call such Convertible Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date, but only with respect to the Convertible Notes called (or deemed called) for redemption;

and (4) upon the occurrence of specified corporate events as set forth in the Indenture.

On or after December 1, 2027, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders of the Convertible Notes may convert all or any portion of their Convertible Notes at any time, regardless of the foregoing circumstances.

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

We may not redeem the Convertible Notes prior to March 6, 2025.

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

In addition, if we undergo a fundamental change (as defined in the indenture governing the Convertible Notes), subject to certain conditions, holders may require us to repurchase for cash all or any portion of their Convertible Notes at a repurchase price equal to 100% of the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid special interest, if any, to, but excluding, the fundamental change repurchase date.

In addition, following certain corporate events that occur prior to the maturity date of the Convertible Notes or if we deliver a notice of redemption in respect of some or all of the Convertible Notes, we will, in certain circumstances, increase the conversion rate of the Convertible Notes for a holder who elects to convert our Convertible Notes in connection with such a corporate event or convert our Convertible Notes called (or deemed called) for redemption during the related redemption period, as the case may be.
