Corte Madera, CA – May 10, 2013 – Restoration Hardware Holdings, Inc. (NYSE: RH) today announced updated guidance for the first quarter of fiscal 2013. For the first quarter of fiscal 2013, the Company now expects net revenues in the range of $295 million to $300 million, representing 35% to 38% growth from the prior year. This compares to the Company’s previous guidance of net revenues in the range of $280 million to $285 million. Comparable store sales for the first quarter of fiscal 2013 are expected to be 41%, on top of the 26% comparable store sales growth reported in the first quarter of fiscal 2012. Adjusted net income for the first quarter of fiscal 2013, excluding the impact of variable non cash stock-based compensation charges of $3.3 million and $700,000 of costs related to the Company’s registration rights agreement with Home Holdings LLC, is now expected to be in the range of $0.9 million to $1.5 million as compared to the previous guidance of a loss of $1 million to breakeven computed on the same basis. Adjusted diluted EPS on the same basis is now expected to be in the range of $0.02 to $0.04 as compared to the Company’s prior guidance in the range of ($0.02) to breakeven. On a GAAP basis, net income for the first quarter of fiscal 2013 is now expected to be in the range of a loss of $1.8 million to a loss of $1.1 million and diluted EPS is now expected to be in the range of ($0.05) to ($0.03). This increase in guidance as compared to the Company’s previously disclosed first quarter guidance on the same basis is expected to be incremental to fiscal 2013 performance. The Company’s earnings and earnings per share guidance for fiscal 2013 does not include (i) an estimate of variable non-cash stock based compensation charges due to uncertainty in predicting fluctuations in stock prices from quarter to quarter or (ii) costs related to the Company’s registration rights agreement with Home Holdings LLC.

Carlos Alberini, Chief Executive Officer, said, “We are very pleased with our business momentum and the revenue and earnings growth we are experiencing this year on top of our record performance in 2012. Our first quarter net revenues were well ahead of our guidance range as we experienced stronger customer response to our product assortment and benefited from our better inventory position, which has enabled us to ship product earlier than anticipated and improve customer service levels.”

Gary Friedman, Chairman Emeritus, Creator and Curator, said, “Our ability to curate and integrate new products, businesses and experiences continues to drive our strong brand position and market leadership. We remain focused on the execution of our growth initiatives, including the transformation of our real estate and the expansion of our offering, and believe we are well positioned to continue to gain market share and further disrupt the highly fragmented home furnishings marketplace.”

The Company has not completed its quarter end closing and review process and the final results for the first quarter fiscal 2013 results may differ from the statements made in this press release. Further commentary on the Company’s first quarter financial results will be provided as part of its first quarter earnings release and conference call.
