Rhea-AI Filing Summary

Shake Shack Inc. reported fiscal first quarter 2026 results showing strong sales growth but slimmer profitability. Total revenue rose 14.3% year-over-year to $366.7 million, driven by $354.0 million of Shack sales and $12.7 million of licensing revenue. System-wide sales reached $558.3 million, up 14.1%, while Same-Shack sales grew 4.6% with traffic up 1.4%, marking a third consecutive quarter of positive traffic.

Restaurant-level profit increased to $75.1 million and margin expanded 50 basis points to 21.2% of Shack sales, reflecting labor efficiencies and supply chain gains despite higher beef costs. However, the company swung to an operating loss of $2.6 million and a net loss of $0.3 million, compared with net income of $4.5 million a year earlier, as general and administrative expenses, pre-opening costs, and other operating expenses rose.

Adjusted EBITDA declined 9.3% to $37.0 million, or 10.1% of total revenue, reflecting higher investments in technology, marketing, and new unit growth. Shake Shack opened 17 new Company-operated Shacks and 5 licensed Shacks in the quarter, ending with 679 system-wide locations, and raised full-year guidance to 60–65 new Company-operated openings and 40–45 licensed openings for 2026.

Insights

Revenue and unit growth remain strong, but higher costs drove a small net loss and softer EBITDA.

Shake Shack delivered solid top-line momentum in Q1 2026, with total revenue at $366.7 million, up 14.3% year-over-year, and Same-Shack sales up 4.6% on 1.4% traffic growth. System-wide sales reached $558.3 million, reflecting both new openings and positive comps.

Profitability, however, tightened. Restaurant-level profit margin improved to 21.2%, but higher general and administrative spending, pre-opening costs, and other operating expenses led to an operating loss of $2.6 million and a net loss of $0.3 million. Adjusted EBITDA fell 9.3% to $37.0 million, or 10.1% of revenue, as the company invested in marketing, technology, and development.

Management increased 2026 development plans to 60–65 Company-operated Shacks and 40–45 licensed Shacks, and highlighted Project Catalyst to modernize systems and launch loyalty. Actual margin progression will depend on executing cost initiatives, managing beef inflation described as high single digits for 2026, and sustaining traffic-driven Same-Shack sales growth.

Key Terms

Restaurant-level profit, Adjusted EBITDA, Same-Shack sales, System-wide sales, +2 more

6 terms

Restaurant-level profit financial

"Restaurant-level profit(1) of $75.1 million, or 21.2% of Shack sales."

Restaurant-level profit is the money a single location generates after paying the costs of running that restaurant—food and drink supplies, staff wages, rent, utilities and other day-to-day expenses—but before corporate overhead, interest, taxes or central investments. Investors use it like a per-store checkup: it shows whether each location’s basic business model is healthy and repeatable, helping judge unit economics, break-even points and how well growth will translate into company-wide profits.

Adjusted EBITDA financial

"Adjusted EBITDA(1) of $37.0 million, down 9.3% versus 2025."

Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.

Same-Shack sales financial

"Same-Shack sales up 4.6% versus 2025."

System-wide sales financial

"System-wide sales of $558.3 million, up 14.1% versus 2025."

Total revenue generated by every outlet in a company’s network, including both company-owned and franchised locations, measured over a given period. Investors watch system-wide sales as a broad indicator of brand demand and growth—like checking the overall temperature of a chain rather than one store—because rising totals suggest the business model and customer base are expanding even if ownership mixes vary.

Project Catalyst technical

"Central to our ongoing productivity is Project Catalyst - the comprehensive technology initiative we announced on April 1st."

tax receivable agreement financial

"Liabilities under tax receivable agreement, net of current portion | 244,613"

A contract in which a company agrees to pay a specified party (often former owners after a spinoff or IPO) a share of future tax savings the company realizes. Think of it like agreeing to share a future tax refund with someone who helped create the conditions for that refund. For investors it matters because those payments reduce the cash the company can use for dividends, buybacks, or reinvestment, and therefore affect valuation and returns.

(UNAUDITED)

To supplement the condensed 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: Restaurant-level profit, Restaurant-level 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").

Restaurant-Level Profit

Restaurant-level 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, Restaurant-level profit and Restaurant-level 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, Restaurant-level profit and Restaurant-level 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 Restaurant-level profit and Restaurant-level 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

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

NON-GAAP FINANCIAL MEASURES

(UNAUDITED)

EBITDA and Adjusted EBITDA

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 excluding equity-based compensation expense, Impairments, loss on the disposal of assets, and Shack closures, 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.

NON-GAAP FINANCIAL MEASURES

(UNAUDITED)

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 (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 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 (loss) 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.

First Quarter 2026 Shareholder Letter

"I’m pleased to report that our first quarter performance showcases continued sales momentum in our Company-operated Shacks and meaningful progress against our six strategic priorities for 2026. We grew total revenue by more than 14%, with Same-Sh ck sales growth of 4.6% and traffic growth of 1.4% - marking our third consecutive quarter of positive traffic. While significant weather impacts pressured our comp by 240 basis points and affected our Adjusted EBITDA for the quarter, our underlying sales and traffic momentum remained strong. Our performance demonstrates the strength of our restaurant operations, culinary innovation that differentiates our brand, and strategic investments in targeted digital media to create awareness of our guest value proposition” said Chief Executive Officer, Rob Lynch. “We also delivered our largest first quarter of new units ever with 17 new Shacks. We continue to successfully bring Shake Shac to new and underpenetrated markets, many outside of our historical footprint. Given ourexpected strong future cash-on-cash returns, we will continue to accelerate our Company-operated development efforts. Consistent with this strategy, we are now guiding to 60-65 new Company-operated Shacks for 2026, an increase from our prior guidance of 55 to 60. Furthermore, we are pleased to see our sales momentum building in the second quarter, with the launch our Smoky BBQ menu platform, anchored by a first-of-its-kind BBQ Boneless Baby Back Rib Sandwich driving strong performance to start May,” concluded Mr. Lynch.

4 TO OUR SHAREHOLDERS Our first quarter results reflect meaningful progressacross our six strategic priorities for 2026. We delivered Total revenue of $366.7 million, growing 14.3% year-over-year. This performance was anchored by same- Shack sales growth of 4.6%, including1.4% traffic growth. These results are particularly encouraging in the face of a challenging macro environment and inclement weather. Despite these pressures, Shake Shackgained market share during the quarter through our balanced approach of combining premium culinary innovation with our strategic value enhancing promotions. During the quarter, Restaurant-level profit margin expanded 50 basis points to 21.2%. This margin expansion came without taking price, despite beef costs rising by low-teens percentages and our continued investment in sales-driving initiatives. The improvement reflects enhanced labor management, supply chain productivity gains, and continued process optimization in our operations. Digital momentum accelerated meaningfully with digital channel guest count and app downloads each growing by more than 35% year-over-year. More importantly, the lifetime value of guests engaging with us through digital channels increased by approximately 20%, powered by higher visit frequency. On theculinary side – building on our successful Korean-i spired platform in January, we introduced our Clubhouse Pimento Cheeseburger and Chicken Sandwich in March. These items exceeded our expectations and performed well nationwide. In late April, we brought back our Smoky BBQ menu platform, featuring our first-of-its-kind BBQ Boneless Baby Back Rib Sandwich alongside a new Mac & Cheese side highlightingour ability to develop and execute premium, differentiated recipes at scale. Our development team opened a record 17 new Company-operated Shacks - our largest Q1in Company history.The strength of our pipeline and the compelling cash-on-cash returns provide the confidence to raise our full-year development guidance to 60-65 new Company-operated Shacks, up from our prior range of 55 to 60. Central to our ongoing productivity is Project Catalyst - the comprehensive technology initiative we announced on April 1st. This multi-year program is designed to support our growth to 1,500 Company-operated Shacks by modernizing our restaurant systems, launching Shake Shack's first loyalty platform, and embedding proprietary AI capabilities into daily operations. We remain confident in the foundation we're building for sustained growth. We have a clear strategy focused on driving same-Shack salesand transaction growth, expanding our footprint with disciplined development, and improving profitability across the enterprise.

LICENSED BUSINESS HIGHLIGHTS 1. Licensing sales is an operating measure and consists of sales from 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 licensed Shacks, as well as certain fees, such as territory fees, opening fees, and termination fees. 6 $179.6M $206.7M $218.7M $232.7M $204.3M Licensing Sales 14% WE GREW LICENSING SALES 14% VERSUS LAST YEAR 10% 16% YoY Licensing Sales Growth 15% 26% 7 9 7 17NSOs Our Licensing revenue grew 14.7% year -over -year to $12.7m and Licensing sales1 grew by 13.8% to $204.3m. We are proud of our strong performance this quarter despite some revenue headwind from our Licensed business in the Middle East. Although the conflictin the Middle East has directly impacted our markets in the region – resulting in temporary closures and reduced operating hours – our teams have shown exceptional resilience, and we have been in close contact to support our partners and maintain safe operations. Sales growth this quarter was driven by new Shack openings and strong comp performance in our United Kingdom and Southeast Asia markets. We opened fivenew licensed Shacks in Q1. We are full steam ahead to bring Shake Shack to Panama, Vietnam, and US regional casinos with PENN Entertainment in the second half of the year and remain on track to open 40 to 45 Shacks in 2026. 1Q25 2Q25 3Q25 4Q25 1Q26 5 Fiscal February 2026 Fiscal March 2026 Fiscal April 2026 Denver International Airport - Terminal A, Denver, USA Trafford Centre, London, United Kingdom Manchester, United KingdomShanghai, ChinaDenver, Colorado, USA InCity MEGA, Shanghai, China The Peak Tower, Hong Kong, China King Street West, Toronto, Canada Avenue of Stars, Hong Kong, China

The month's same-Shack sales were negatively impacted by approximately 200 bps largely due to the shift of Easter week and spring breaks into March this year compared to last.

8 RESTAURANT - LEVEL PROFIT Restaurant -level costs in the first quarter (covered in more detail on the following pages) were as follows: • Food and paper costs were 28.3% of Shack sales. • Labor and related expenses were 26.2% of Shack sales. • Other operating expenses were 16.2% of Shack sales. • Occupancy and related expenses were 8.1% of Shack sales. We continued to see year-over-year margin expansion driven by strong benefits from our labor management strategies, cost declines in other commodities across our basket that helped offset higher beef costs compared to last year, and investments in sales-dr ving initiatives. During Q1, we opened a record of 17 new Shacks, accelerating our pace of development for 2026 to 60-65 openings fromprior range of 55-60. Restaurant-level margins came in slightly below our expectations for the quarter due to higher Other operating expenses, mainly due to the timing of investments in repairs and maintenance expenses to support our Shacks, increased costs associated with pulling forward new Shack openings into Q1and some mix impact of our marketing initiatives. 1.

Other operating expenses (“Other opex ”) were 16.2% of Shack sales in the first quarter, up 60 bps year-over-year.

Fiscal second quarter and fiscal year 2026 guidance is derived from preliminary, unaudited results based on information currently available to the Company. We factor in an assumption around a degree of pressure on the consumer spending landscape and ongoing inflationary headwinds and do not reflect any change in the current environment including potential changes to tariffs, amongst other factors. While the Company believes these estimates are meaningful, they could differ from the actual results that the Company ultimatelyreports in its Quarterly Report on Form 10-Q for the fiscal quarter ending April 1, 2026 and its Annual Report on Form 10-K for the fiscal year ending December 30, 2026.

DEFINITIONS 16 The following definitions, and definitions on the subsequent pages, apply to terms as used in this shareholder letter: "Shack sales" is defined as the aggregate sales of food, beverages, gift card breakage income, and Shake Shack branded merchandise at Company-operated Shacks and excludes sales from licensed Shacks. “System-wide sales” is an operating measure and consists of sales from Company-operated Shacks and licensed Shacks. The Company does not recognize the sales from licensed Shacks as revenue. Of these amounts, revenue is limited to licensing revenue based on a percentage of sales from licensed Shacks, as well as certain up-front fees, such as territory fees, opening fees, and termination fees. "Same-Shack sales" or “SSS” represents Shack sales for the comparable Shack base, which is defined as the number of Company- operated Shacks open for 24 full fiscal months or longer. For consecutive days that Shacks were temporarily closed, the comparative period was also adjusted. "Average weekly sales" or “AWS” 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. “Adjusted pro forma net income," a non-GAAP measure, represents Net income 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 and may not be indicative of the Company’s recurring business operations. “EBITDA,” a non-GAAP measure, is defined as Net income before interest expense (net of interest income), Income tax expense, and Depreciation and amortization expense. “Adjusted EBITDA,” a non-GAAP measure, is defined as EBITDA (as defined above), excluding equity-based compensation expense, Impairments, loss on disposal of assets and Shack closures, 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 before interest expense (net of interest income), Income tax expense and Depreciation and amortization expense, which also excludes equity-based compensation expense, Impairments, loss on disposal of assets and Shack closures, 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, as a percentage of Total revenue. “Restaurant-level 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. "Restaurant-level 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.

RESTAURANT -LEVEL PROFIT DEFINITIONS 21 Restaurant -Level Profit “Restaurant-level 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. Restaurant -level Profit Margin "Restaurant-level 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. How This Measure Is Useful When used in conjunction with GAAP financial measures, Restaurant-level profit and Restaurant-level profit margin are supplemental measures of operating performance that the Company believes are useful measures to evaluate the performance and profitability of its Shacks. Additionally, Restaurant-level profit and Restaurant-level profit margin are key metrics used interally 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 Restaurant-level profit and Restaurant-level 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-maki g. Limitations of the Usefulness of this Measure Restaurant-level profit and Restaurant-level profit margin may differ from similarly titled measures used by other companies due to different methods of calculation. Presentation of Restaurant-level profit and Restaurant-level profit margin is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP. Restaurant-level profit excludes certain costs, such as General and administrative expenses and Pre-opening costs, which are considered normal, recurring cash operating expenses and are essential to support the operation and development of the Company's Shacks. Therefore, this measure may not provide a complete understanding of the Company's operating results as a whole and Restaurant-level profit and Restaurant-level profit margin should be reviewed in conjunction with the Company’s GAAP financial results. A reconciliation of Restaurant-level profit to operating income, the most directly comparable GAAP financial measure, is set forth on next slide.

EBITDA and Adjusted EBITDA EBITDA, a non-GAAP measure, is defined as Net income before interest expense (net of interest income), Income tax expense and Depreciation and amortization expense. Adjusted EBITDA, a non-GAAP measure, is defined as EBITDA (as defined above) excluding equity-based compensation expense, Impairments, loss on disposal of assets and Shack closures, 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, the most directly comparable GAAP measure, is set forth on next slide. ADJUSTED EBITDA DEFINITIONS 23

Adjusted Pro Forma Net Income and Adjusted Pro Forma Earnings Per Fully Exchanged and Diluted Share Adjusted pro forma net income represents Net income 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 and earnings 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.

Adjusted Pro Forma Effective Tax Rate Adjusted pro forma effective tax rate represents the effective tax rate 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-recurri g items that the Company does not believe are directly related to its core operations and may not be indicative of its recurring business operations. How This Measure Is Useful When used in conjunction with GAAP financial measures, adjusted pro forma effective tax rate is a supplemental measure of operating performance that the Company believes is useful to evaluate its performance period over period and relative to its competitors. By assuming the full exchange of all outstanding LLC Interests, the Company believes this measure facilitates comparisons with other companies that have different organizational and tax structures, as well as comparisons period over peri d because it eliminates the effect of any changes in effective tax rate driven by increases in its ownership of SSE Holdings, wh ch 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 this Measure Adjusted pro forma effective tax rate may differ from similarly titled measures used by other companies due to different methods of calculation. Presentation of adjusted pro forma effective tax rate should not be considered an alternative to effective tax ra e, as determined under GAAP. While this measure is useful in evaluating the Company's performance, itdo s not account for the effective tax rate attributable to the non-c trolling interest holders and therefore does not provide a complete understanding of effective tax rate. Adjusted pro forma effective tax rate should be evaluated in conjunction with GAAP financial results. A reconciliation of adjusted pro forma effective tax rate, the most directly comparable GAAP measure, is set forth on next slide. ADJUSTED PRO FORMA EFFECTIVE TAX RATE DEFINITIONS 27
