Item 2.02. Results of Operations and Financial Condition.

On October 31, 2011, Winn-Dixie Stores, Inc. (the “Company”) issued a press release providing financial results for the 12 weeks ended September 21, 2011. A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated herein by reference. As used herein, the words, “we,” “our,” and “us” refer to the Company and its subsidiaries.

In the press release and in our other public statements in connection with the press release, as well as in analyzing and planning for our business, we supplement our use of financial measures that are calculated and presented in accordance with generally accepted accounting principles (“GAAP”) with the non-GAAP financial measure Adjusted EBITDA. Adjusted EBITDA is net income or loss adjusted to exclude discontinued operations, income taxes, interest income, interest expense, depreciation, amortization, impairment charges, certain non-cash charges related to the Company’s compensation programs, adjustments to the Company’s self insurance reserve, non-recurring gains, and items related to the Company’s emergence from bankruptcy.

Adjusted EBITDA is presented because we believe that it is an important metric for evaluating our operating performance. Moreover, Adjusted EBITDA facilitates comparison of our results of operations with companies in our industry that may have different capital structures. EBITDA excludes the effects of financing and investing activities by eliminating the effects of interest, income taxes, depreciation, and amortization. Excluding the non-cash charges related to the Company’s compensation programs, impairment charges, adjustments to the Company’s self insurance reserve, non-recurring gains, and items related to the Company’s emergence from bankruptcy further helps to isolate operating performance and to facilitate such comparisons, inasmuch as the items excluded are not a function of our current operating performance and affect our GAAP results regardless of our performance. In addition, certain of these items may vary significantly from period to period and may have a disproportionate effect in a given period, which may affect the comparability of the results.

In addition, we use the non-GAAP measure “Cash operating and administrative expenses” because management uses this for planning and forecasting future periods. Cash operating and administrative expenses is defined as operating and administrative expenses from continuing operations adjusted for depreciation, amortization, non-cash charges related to the Company’s compensation programs, and adjustments to the Company’s self insurance reserve. The Company believes the presentation of this measure is relevant and useful for investors because it allows investors to view results in a manner similar to the method used by the Company’s management.

Investors are cautioned that the usefulness of Adjusted EBITDA and Cash operating and administrative expenses are limited by the fact that they exclude items which have or have had an effect on our overall financial performance, including the effects of our capital structure, the nature of our assets and liabilities, our equity compensation programs, restructuring efforts that we have taken and our bankruptcy and subsequent

emergence. Due to these limitations, we use Adjusted EBITDA and Cash operating and administrative expenses only in addition to and in conjunction with results presented in accordance with GAAP. We strongly encourage investors to review our consolidated financial statements and publicly filed reports in their entirety and not to rely on any single financial measure. Further, because non-GAAP financial measures are not standardized, it may not necessarily be possible to compare our use of Adjusted EBITDA and Cash operating and administrative expenses with non-GAAP financial measures having the same or similar names used by other companies.
