We believe 2026 is going to be a transformational year for Wingstop and remain extremely confident in the long-term opportunity in front of us as we continue to scale into a top 10 global restaurant brand.”

Q1 2026 Financial Results

Total revenue for the first quarter 2026 increased to $183.7 million from $171.1 million in the prior first quarter. Royalty revenue, franchise fees and other increased $8.7 million, of which $12.2 million was due to net new franchise development and $3.4 million related to an increase in vendor rebates, partially offset by a decrease of $5.9 million due to an 8.7% decline in domestic same store sales contributed by lower transaction volumes, reflecting continued pressure on consumer spending. Advertising fees increased $1.0 million due to a 5.9% increase in system-wide sales in the first quarter 2026. Company-owned restaurant sales increased $2.9 million due to the six additional corporate stores opened or acquired since the prior year period.

Cost of sales was $24.7 million compared to $22.8 million in the prior first quarter. As a percentage of company-owned restaurant sales, cost of sales decreased to 74.9% from 76.0% in the prior first quarter. The decrease as a percentage of company-owned restaurant sales was primarily driven by a decline in food, beverage and packaging costs, reflecting a decrease in the cost of bone-in chicken wings as compared to the prior first quarter.

Selling, general & administrative (“SG&A”) expense increased $3.0 million to $34.4 million from $31.4 million in the prior first quarter. The increase in SG&A expense was primarily driven by $2.4 million in restructuring charges related to the corporate realignment announced during the fiscal first quarter 2026, partially offset by lower system implementation costs and other expenses compared to the prior year period.

The prior fiscal first quarter included investment income of $93.8 million in the prior fiscal first quarter. This was related to the $97.2 million gain on the sale of our non-controlling interest in Lemon Pepper Holdings, Ltd. (“LPH”), Wingstop’s United Kingdom master franchisee, recognized in the prior year period.

Income tax expense was $10.7 million, yielding an effective tax rate of 26.3%, comparable to 25.1% in the prior fiscal first quarter. The decrease in total tax expense is primarily due to the absence of the prior year taxable gain on the sale of our non-controlling interest in LPH.

On February 18, 2026, Wingstop Inc. (the “Company,” “we,” “our,” or “us”) issued a press release reporting the Company’s financial results for its fiscal fourth quarter ended December 27, 2025. A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated by reference herein in its entirety. The press release uses the U.S. generally accepted accounting principles (“GAAP”) measures of net income and earnings per diluted share and the following non-GAAP financial measures: EBITDA, Adjusted EBITDA, Adjusted net income and Adjusted earnings per diluted share. A discussion of these non-GAAP financial measures, including a discussion of the usefulness and purpose of each measure, is included below. EBITDA and Adjusted EBITDA. EBITDA and Adjusted EBITDA are supplemental measures of our performance that are not required by, or presented in accordance with, GAAP. EBITDA and Adjusted EBITDA are not measurements of our financial performance under GAAP and should not be considered as alternatives to net income or any other performance measure derived in accordance with GAAP, or as alternatives to cash flows from operating activities as a measure of our liquidity. We define “EBITDA” as net income before interest expense, net, income tax expense (benefit), and depreciation and amortization. We define “Adjusted EBITDA” as EBITDA further adjusted for losses on debt extinguishment and financing transactions, transaction costs, costs and fees associated with investments in our strategic initiatives, gains and losses on non-recurring transactions, certain system implementation costs, and stock-based compensation expense. We present EBITDA and Adjusted EBITDA because we consider them to be important supplemental measures of our performance and believe they are frequently used by securities analysts, investors, and other interested parties in the evaluation of companies in our industry. Management believes that investors’ understanding of our performance is enhanced by including these non-GAAP financial measures as a reasonable basis for comparing our ongoing results of operations.

We present EBITDA and Adjusted EBITDA because we consider them to be important supplemental measures of our performance and believe they are frequently used by securities analysts, investors, and other interested parties in the evaluation of companies in our industry. Management believes that investors’ understanding of our performance is enhanced by including these non-GAAP financial measures as a reasonable basis for comparing our ongoing results of operations. Many investors are interested in understanding the performance of our business by comparing our results from ongoing operations on a period-over-period basis and would ordinarily add back non-cash expenses such as depreciation and amortization, as well as items that are not part of normal day-to-day operations of our business.

The following information is furnished pursuant to Item 2.02, “Results of Operations and Financial Condition.” Consequently, it shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or otherwise subject to the liabilities of that section, nor shall such information be deemed incorporated by reference in any filing under the Exchange Act or the Securities Act of 1933, as amended (the “Securities Act”), except as shall be expressly set forth by specific reference in such filing.

A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated by reference herein in its entirety. The press release uses the U.S. generally accepted accounting principles (“GAAP”) measure of net income and the non-GAAP financial measures of EBITDA and Adjusted EBITDA.

We define “EBITDA” as net income before interest expense, net, income tax expense (benefit), and depreciation and amortization. We define “Adjusted EBITDA” as EBITDA further adjusted for losses on debt extinguishment and financing transactions, transaction costs, costs and fees associated with investments in our strategic initiatives, system implementation costs, and stock-based compensation expense.

Item 2.02.Results of Operations and Financial Condition

The following information is furnished pursuant to Item 2.02, “Results of Operations and Financial Condition.” Consequently, it shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or otherwise subject to the liabilities of that section, nor shall such information be deemed incorporated by reference in any filing under the Exchange Act or the Securities Act of 1933, as amended (the “Securities Act”), except as shall be expressly set forth by specific reference in such filing. On May 3, 2023, Wingstop Inc. (the “Company,” “we,” “our,” or “us”) issued a press release reporting the Company’s financial results for its fiscal first quarter ended April 1, 2023. A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated by reference herein in its entirety. The press release uses the U.S. generally accepted accounting principles (“GAAP”) measures of net income and earnings per diluted share and the following non-GAAP financial measures: EBITDA, Adjusted EBITDA, Adjusted net income and Adjusted earnings per diluted share. A discussion of these non-GAAP financial measures, including a discussion of the usefulness and purpose of each measure, is included below. EBITDA and Adjusted EBITDA. EBITDA and Adjusted EBITDA are supplemental measures of our performance that are not required by, or presented in accordance with, GAAP. EBITDA and Adjusted EBITDA are not measurements of our financial performance under GAAP and should not be considered as alternatives to net income or any other performance measure derived in accordance with GAAP, or as alternatives to cash flows from operating activities as a measure of our liquidity. We define “EBITDA” as net income before interest expense, net, income tax expense (benefit), and depreciation and amortization. We define “Adjusted EBITDA” as EBITDA further adjusted for losses on debt extinguishment and financing transactions, transaction costs, costs and fees associated with investments in our strategic initiatives, and stock-based compensation expense. We present EBITDA and Adjusted EBITDA because we consider them to be important supplemental measures of our performance and believe they are frequently used by securities analysts, investors, and other interested parties in the evaluation of companies in our industry. Management believes that investors’ understanding of our performance is enhanced by including these non-GAAP financial measures as a reasonable basis for comparing our ongoing results of operations. Many investors are interested in understanding the performance of our business by comparing our results from ongoing operations on a period-over-period basis and would ordinarily add back non-cash expenses such as depreciation and amortization, as well as items that are not part of normal day-to

Item 1.01. Entry into a Material Definitive Agreement

General As previously announced, on March 2, 2022, Wingstop Inc. (the “Company,” “we,” “our,” or “us”) entered into a definitive agreement relating to an existing securitized financing facility pursuant to a privately placed securitization transaction (the “2022 Securitization”). To complete the 2022 Securitization, on March 9, 2022 (the “Closing Date”), Wingstop Funding LLC, a Delaware limited liability company (the “Issuer”), a limited purpose, bankruptcy-remote, indirect wholly owned subsidiary of the Company issued $250 million of its Series 2022-1 3.734% Fixed Rate Senior Secured Notes, Class A-2 (the “2022 Class A-2 Notes”). The offering was exempt from registration under the Securities Act of 1933, as amended (the “Securities Act”). In connection with the issuance of the 2022 Class A-2 Notes, the Issuer also entered into a revolving financing facility of Series 2022-1 Variable Funding Senior Notes, Class A-1 (the “2022 Variable Funding Notes”), which permits borrowings of up to a maximum principal amount of $200 million, a portion of which may be used to issue letters of credit. The 2022 Class A-2 Notes and the 2022 Variable Funding Notes are referred to collectively as the “2022 Notes.” Subject to certain limitations, the 2022 Notes are secured by certain of the Company’s domestic and foreign revenue-generating assets, consisting principally of franchise-related agreements, intellectual property, and vendor rebate contracts (collectively, the “Securitized Assets”), that were previously contributed or otherwise transferred to the Issuer and certain other limited-purpose, bankruptcy-remote, wholly owned indirect subsidiaries of the Company (collectively, the “Securitization Entities”) that act as guarantors pursuant to a guarantee and collateral agreement previously entered into. 2022 Class A-2 Notes The 2022 Class A-2 Notes were issued under a Second Amended and Restated Base Indenture (the “Base Indenture”) and the related Series 2022-1 Supplement thereto (the “Series 2022-1 Supplement”), each dated March 9, 2022, by and between the Issuer and Citibank, N.A., as trustee (in such capacity, the “Trustee”) and securities intermediary. The Base Indenture and the Series 2022-1 Supplement (collectively with the Series 2020 Supplement previously entered into, the “Indenture”) will allow the Issuer to issue additional series of notes in the future, subject to certain conditions set forth therein. Interest and principal payments on the 2022 Class A-2 Notes are payable on a quarterly basis. The requirement to make such quarterly principal payments on the 2022 Class A-2 Notes is subject to certain financial conditions set forth in the Indenture. The legal final maturity date of the 2022 Class A-2 Notes is in March of 2052, but, unless earlier prepaid to the extent permitted under the Indentu
