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 July 29, 2026, Wingstop Inc. (the “Company,” “we,” “our,” or “us”) issued a press release reporting the Company’s financial results for its fiscal second quarter ended June 27, 2026. 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, certain restructuring charges, 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-day operations of our business. Management uses EBITDA and Adjusted EBITDA: • as a measurement of operating performance because we believe they assist management in comparing the operating performance of our restaurants on a consistent basis, as they remove the impact of items not directly resulting from our core operations; • for planning purposes, including the preparation of our internal annual operating budget and financial projections; • to evaluate the performance and effectiveness of our operational strategies; • to evaluate our capacity to fund capital expenditures and expand our business; and • to calculate incentive compensation payments for our employees, including assessing performance under our annual incentive compensation plan. By providing these non-GAAP financial measures, together with a reconciliation to the most comparable GAAP measure, we believe we are enhancing investors’ understanding of our business and our results of operations, as well as assisting investors in evaluating how well we are executing our strategic initiatives. EBITDA and Adjusted EBITDA have limitations as analytical tools and should not be considered in isolation, or as an alternative to, or a substitute for, net income or other financial statement data presented in our consolidated financial statements as indicators of financial performance. Some of the limitations include, but are not limited to, the following: • such measures do not reflect our cash expenditures, or future requirements for capital expenditures or contractual commitments; • such measures do not reflect changes in, or cash requirements for, our working capital needs; • such measures do not reflect the interest expense, or the cash requirements necessary to service interest or principal payments, on our debt; • such measures do not reflect our tax expense or the cash requirements to pay our taxes; • although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future and such measures do not reflect any cash requirements for such replacements; and • other companies in our industry may calculate such measures differently than we do, limiting their usefulness as comparative measures. Due to these and other limitations, EBITDA and Adjusted EBITDA should not be considered as measures of discretionary cash available to us to invest in the growth of our business. We compensate for these limitations by relying primarily on our GAAP results and using these non-GAAP measures only as performance measures and supplementally. As noted in the press release attached hereto as Exhibit 99.1, Adjusted EBITDA includes adjustments 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, certain restructuring charges, and stock-based compensation expense. We believe these adjustments are appropriate because the amounts recognized can vary significantly from period-to-period, do not directly relate to the ongoing operations of our restaurants, and complicate comparisons of our internal operating results and operating results of other restaurant companies over time. Adjusted Net Income and Adjusted Earnings Per Diluted Share. Adjusted net income represents net income 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, certain restructuring charges, and related tax adjustments that management believes are not indicative of the Company’s core operating results or business outlook over the long-term. Adjusted earnings per diluted share is defined as adjusted net income divided by weighted average diluted share count. Adjusted net income and adjusted earnings per diluted share are supplemental measures of operating performance that do not represent and should not be considered alternatives to net income and earnings per diluted share, as determined by GAAP. These measures have not been prepared in accordance with Article 11 of Regulation S-X promulgated under the Securities Act. Management believes adjusted net income and adjusted earnings per diluted share supplement GAAP measures and enable management to more effectively evaluate the Company’s performance period-over-period and relative to competitors. We caution investors that amounts presented in accordance with our definitions may not be comparable to similar measures disclosed by our competitors because not all companies and analysts calculate certain non-GAAP measures in the same manner.
