Balance Sheet and Liquidity

As of August 3, 2013, the Company had $50.8 million of cash and marketable securities and no borrowings or debt outstanding on its revolving credit facility.

Third Quarter 2013 Outlook

We expect comparable store sales to be flat compared to a 1.9% comparable store sales increase in the third quarter of 2012. Using an anticipated effective tax rate of 40%, net income for the third quarter is expected to be in the range of $5.4 million to $6.3 million, or $0.19 to $0.22 per diluted share, and assumes a weighted average diluted share count of 28.3 million shares, compared to 28.1 million weighted average diluted shares in the third quarter of last year.

Third quarter 2012 adjusted net income was $8.3 million, which includes a 40% effective tax rate to make that quarter comparable. (See reconciliation of non-GAAP results to GAAP results at the end of this release.)

Fiscal Year 2013 Outlook

The Company continues to expect comparable store sales growth in the low-single digit range for fiscal 2013, on a 52-week vs. 52-week basis. Using an anticipated full year effective tax rate of 40%, net income for fiscal year 2013 is expected to be in the range of $21.5 million to $23.3 million, or $0.76 to $0.82 per diluted share, and assumes a weighted average diluted share count of 28.2 million shares, compared to 26.1 million weighted average diluted shares for the full year 2012.

Full year 2012 adjusted net income was $22.9 million, which includes four quarters of ongoing stock-based compensation expense totaling $2.7 million and a 40% effective tax rate for the entire year, and excludes the one-time SG&A charge and the one-time tax benefit resulting from the conversion to a “C” corporation described above.

Non-GAAP Financial Measures

In addition to reporting financial measures in accordance with accounting principles generally accepted in the United States (“GAAP”), the Company provides certain non-GAAP financial measures including “adjusted selling, general and administrative expenses”, “adjusted operating income”, “adjusted income before income taxes”, “adjusted income tax provision”, “adjusted net income”, “adjusted basic earnings per share” and “adjusted diluted earnings per share”. These amounts are not in accordance with, or an alternative to, GAAP. The Company’s management believes that these measures provide investors with transparency by helping illustrate the financial results: (i) as if the Company had been a publicly traded “C” Corporation during the relevant time periods, in order to provide a better comparison of past periods to current periods as a “C” Corporation; and (ii) to exclude items that may not be indicative of, or are unrelated to, the Company’s core operating results, providing a better baseline for analyzing trends in the underlying business.

For a description of these non-GAAP financial measures and reconciliations of these non-GAAP financial measures to the most directly comparable financial measures prepared in accordance with GAAP, please see the accompanying table titled “ Supplemental Information - Consolidated Statements of Income; Reconciliation of Non-GAAP Financial Measures to GAAP Financial Measures” contained in this press release.
