(1) Adjusted EBITDA, adjusted net income and adjusted diluted earnings per share are non-GAAP financial measures, which exclude the impact of certain special items. Please note that our non-GAAP financial measures should be considered as a supplement to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. See the "Non-GAAP Financial Information" section of this release as well as the respective reconciliations of our non-GAAP financial measures below for additional information about these items.

•Cash and cash equivalents totaled $82.1 million at the end of the first quarter of fiscal 2023.

•On February 21, 2023, the Company completed the refinancing of its credit facility in order to lower borrowing costs and increase both liquidity and financial flexibility. The new facility includes a $300.0 million term loan and a $400.0 million revolving credit facility. At closing, the term loan was borrowed in full and $25.0 million was drawn against the revolving credit facility. Total debt was $323.1 million at the end of the first quarter of fiscal 2023, net of unamortized debt issuance costs.

The Company is revising its fiscal 2023 outlook on key metrics as follows:

A conference call to discuss the first quarter fiscal 2023 financial results is scheduled for today, May 9, 2023 at 4:30 p.m. Eastern Time. Investors and analysts interested in participating in the call are invited to dial (877) 407-9208 approximately 10 minutes prior to the start of the call, using conference ID #13730481. A live audio webcast of the conference call will be available online at https://investors.groceryoutlet.com.

A taped replay of the conference call will be available within two hours of the conclusion of the call and can be accessed both online and by dialing (844) 512-2921 and entering access code 13730481. The replay will be available for approximately two weeks after the call.

In the first quarter of fiscal 2023, in order to enhance the comparability of our results with our peers, we updated our presentation of the condensed consolidated statements of operations and comprehensive income to include depreciation and amortization expenses and share-based compensation expenses within selling, general and administrative expenses. Prior period amounts have been reclassified to conform to current period presentation. The reclassification of these items had no impact on net income, earnings per share, or retained earnings in the current or prior periods.

In addition to reporting financial results in accordance with accounting principles generally accepted in the United States ("GAAP"), the Company uses EBITDA, adjusted EBITDA, adjusted net income and adjusted earnings per share as supplemental measures of performance to evaluate the effectiveness of its business strategies, to make budgeting decisions and to compare its performance against that of other peer companies using similar measures. In addition, the Company uses adjusted EBITDA to supplement GAAP measures of performance to evaluate performance in connection with compensation decisions. Management believes it is useful to investors and analysts to evaluate these non-GAAP measures on the same basis as management uses to evaluate the Company's operating results. Management believes that excluding items from operating income, net income and net income per diluted share that may not be indicative of, or are unrelated to, the Company's core operating results, and that may vary in frequency or magnitude, enhances the comparability of the Company's results and provides additional information for analyzing trends in the business.

Adjusted EBITDA is defined as net income before net interest expense, income taxes, depreciation and amortization expenses ("EBITDA") and adjusted to exclude share-based compensation expense, loss on debt extinguishment and modification, asset impairment and gain or loss on disposition and certain other expenses that may not be indicative of, or are unrelated to, the Company's core operating results, and that may vary in frequency or magnitude. Adjusted net income represents net income adjusted for the previously mentioned adjusted EBITDA adjustments, further adjusted for costs related to amortization of purchase accounting assets and deferred financing costs, tax adjustment to normalize the effective tax rate, and tax effect of total adjustments. Basic adjusted earnings per share is calculated using adjusted net income, as defined above, and basic weighted average shares outstanding. Diluted adjusted earnings per share is calculated using adjusted net income, as defined above, and diluted weighted average shares outstanding.

EBITDA, adjusted EBITDA, adjusted net income and adjusted earnings per share are non-GAAP measures and may not be comparable to similar measures reported by other companies. EBITDA, adjusted EBITDA, adjusted net income and adjusted earnings per share have limitations as analytical tools, and you should not consider them in isolation or as a substitute for analysis of the Company's results as reported under GAAP. The Company addresses the limitations of the non-GAAP measures through the use of various GAAP measures. In the future the Company will incur expenses or charges such as those added back to calculate adjusted EBITDA or adjusted net income. The presentation of EBITDA, adjusted EBITDA, adjusted net income and adjusted earnings per share should not be construed as an inference that future results will be unaffected by the adjustments used to derive these non-GAAP measures.

Beginning with the fourth quarter of fiscal 2022, we updated our definitions of adjusted EBITDA, adjusted net income and adjusted earnings per share to no longer exclude the impact of non-cash rent expense and the provision for accounts receivable reserves. See the "Operating Metrics and Non-GAAP Financial Measures" section of our Annual Report on Form 10-K for the fiscal year ended December 31, 2022 for more information.

The Company has not reconciled the non-GAAP adjusted EBITDA and adjusted diluted earnings per share forward-looking guidance included in this release to the most directly comparable GAAP measures because this cannot be done without unreasonable effort due to the variability and low visibility with respect to taxes and non-recurring items, which are potential adjustments to future earnings. We expect the variability of these items to have a potentially unpredictable, and a potentially significant, impact on our future GAAP financial results.
