Item 2.02. Results of Operations and Financial Condition.

On September 17, 2015, Rite Aid Corporation (the “Company”) reported its financial position and results of operations as of and for the thirteen and twenty-six week period ended August 29, 2015 (the second quarter of fiscal 2016). The press release includes a non-GAAP financial measure, “Adjusted EBITDA.” The Company uses this non-GAAP measure in assessing its performance in addition to net income determined in accordance with GAAP.

The Company believes Adjusted EBITDA serves as an appropriate measure in evaluating the performance of its business and helps its investors better compare the Company’s operating performance with its competitors. The Company defines Adjusted EBITDA as net income excluding the impact of income taxes (and any corresponding adjustment to tax indemnification asset), interest expense, depreciation and amortization, LIFO adjustments, charges or credits for facility closing and impairment, inventory write-downs related to store closings, debt retirements and other items (including stock-based compensation expense, sale of assets and investments and revenue deferrals related to the Company’s customer loyalty program). The Company references this non-GAAP financial measure frequently in its decision-making because it provides supplemental information that facilitates internal comparisons to historical periods and external comparisons to competitors. In addition, incentive compensation is based in part on Adjusted EBITDA and the Company bases certain of its forward-looking estimates and budgets on Adjusted EBITDA.

Adjusted EBITDA should not be considered in isolation from, and is not intended to represent an alternative measure of, operating results or of cash flows from operating activities, as determined in accordance with GAAP. The Company’s definition of Adjusted EBITDA may not be comparable to similarly titled measurements reported by other companies or similar terms in the Company’s debt facilities. The press release attached hereto as Exhibit 99.1 includes a reconciliation of Adjusted EBITDA to net income, the most directly comparable GAAP financial measure.

Item 9.01. Financial Statements and Exhibits.

(d) Exhibits.
