Tilly’s, Inc. Reports Holiday Sales

• Updates Fourth Quarter and Full Year 2012 Outlook

Irvine, CA – January 10, 2013 – Tilly’s, Inc. (NYSE: TLYS) today announced that comparable store sales, which include e-commerce sales, for the “Holiday” period (ten weeks ended January 5, 2013) decreased 1%, compared to a 5% increase for the “Holiday” period in the prior year (ten weeks ended January 7, 2012).

Daniel Griesemer, President and Chief Executive Officer, commented, “Our quarter-to-date sales reflect strong comparable store sales results in the peak weekend of Black Friday/Cyber Monday and in late December/early January, with soft traffic and sales in between. We have exited the holiday season with our inventory well positioned, having maintained our strong pricing discipline and brand integrity. We transition into Spring with complete confidence in our business model and remain focused on long-term quality growth.”

Fourth Quarter 2012 Outlook

Based on the results for the Holiday period, GAAP net income for the fourth quarter using the anticipated effective tax rate of 32.9% is expected to be in the range of $9.0 million to $9.3 million, or $0.32 to $0.33 per diluted share, and assumes a diluted share count of 28.2 million shares, compared to 20.5 million diluted shares in the fourth quarter of last year. The Company’s 2012 fourth quarter includes one additional week compared to last year, and our 2012 fiscal year is a 53-week year compared to a 52-week fiscal 2011.

On an adjusted basis, using an anticipated on-going effective tax rate of 40%, adjusted net income in the fourth quarter is expected to be in the range of $8.1 million to $8.4 million, or $0.29 to $0.30 per diluted share.

Fiscal Year 2012 Outlook
