3rd Quarter and Year-to-Date Comparable Store Sales Results

Comparable store sales are calculated based on the change in sales for stores open at least one year and exclude sales of

specialty machinery, sales to independent parts stores, sales to Team Members and sales from the acquired VIP stores due to the significant change in the business model and lack of historical data. Comparable store sales increased 4.6% for the third quarter ended September 30, 2013, versus 1.3% for the same period one year ago. Comparable store sales increased

3.9% for the first nine months of 2013, versus 3.7% for the same period one year ago.

Non-GAAP Information

This release contains certain financial information not derived in accordance with United States generally accepted

accounting principles ("GAAP"). These items include adjusted net income, rent-adjusted debt to adjusted earnings before interest, taxes, depreciation, amortization, share-based compensation and rent ("EBITDAR") and free cash flow. The Company does not, nor does it suggest investors should, consider such non-GAAP financial measures in isolation from, or as a substitute for, GAAP financial information. The Company believes that the presentation of financial results and estimates excluding the impact of the former CSK Auto Corporation ("CSK") officer clawback, as well as the presentation of adjusted debt to adjusted EBITDAR and free cash flow provide meaningful supplemental information to

both management and investors that is indicative of the Company's core operations. The Company excludes this item in judging its performance and believes this non-GAAP information is useful to investors as well. The Company has included a reconciliation of this additional information to the most comparable GAAP measure in the selected financial information below.
