Corte Madera, CA – September 10, 2014 – Restoration Hardware Holdings, Inc. (NYSE:RH) today announced record financial results for the second quarter ended August 2, 2014.

Second Quarter Highlights

Gary Friedman, Chairman and Chief Executive Officer, commented, “Our ability to innovate, curate and integrate new products, categories and businesses, then test and rapidly scale them across our multi-channel platform, is at the core of RH becoming a disruptive brand in the home furnishings marketplace. In the second quarter, we achieved a record operating margin of 11.3%, a 240 basis point improvement versus last year, and the driver of our earnings over-performance. Comparable brand revenue for the quarter increased 13% on top of a 30% increase a year ago – representing an industry-best 43% gain over the two-year period.”

Mr. Friedman added, “We are very pleased with the early results from our new 2014 Source Books. While still early in reading the results, as the books were in homes seven weeks later than last year, the business has continued to accelerate into the second half which gives us the confidence to increase earnings guidance for the year. We did experience a sales shortfall during our Fourth of July Promotional Event as we underestimated the negative effect of the later Source Book mailing which led to lower than expected revenues in the second quarter. Post the event, our business remains strong and we expect it to continue building as we roll out some of the tested, new collections into our stores beginning this week. Additionally, our historical data implies that our new product offer will continue to accelerate for several more weeks post the book drop and as our in-stock positions improve.”

Mr. Friedman continued, “Looking forward, we remain focused on our key value driving strategies including the expansion of our product offer, the transformation of our retail stores, and the continued enhancement of our multi-channel platform and operating infrastructure. Regarding the transformation of our retail stores, we will be opening a new, larger Full Line Design Gallery on Melrose Avenue in Los Angeles and our first next generation Full Line Design Gallery in Atlanta later this year. We now have signed leases for 8 next generation Full Line Design Galleries and have identified and are in negotiations for more than 30 additional locations.”

Mr. Friedman concluded, “From the continued evolution of our Source Books, to the transformative economics of our Full Line Design Galleries, to how we source, price, present and deliver products across our multi-channel platform, we are constantly evolving and working to create a superior business model. While still in the early stages of building RH into the leading luxury home brand, we are well on track towards our long-term goal of $4 billion to $5 billion in North American sales, mid-teens operating margin, and generating significant free cash flow.”

*Non-GAAP Financial Measures

To supplement its condensed consolidated financial statements, which are prepared and presented in accordance with Generally Accepted Accounting Principles (“GAAP”), the Company uses the following non-GAAP financial measures: adjusted operating income, adjusted operating margin, adjusted net income, adjusted EPS, and adjusted diluted EPS (collectively, “non-GAAP financial measures”). We compute these measures by adjusting the applicable GAAP measures to remove the impact of certain recurring and non-recurring charges and gains and the tax effect of these adjustments. The presentation of this financial information is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP. The Company uses these non-GAAP financial measures for financial and operational decision making and as a means to evaluate period-to-period comparisons. The Company believes that they provide useful information about operating results, enhance the overall understanding of past financial performance and future prospects, and allow for greater transparency with respect to key metrics used by management in its financial and operational decision making. The non-GAAP financial measures used by the Company in this press release may be different from the methods used by other companies.

For more information on the non-GAAP financial measures, please see the Reconciliation of GAAP to non-GAAP Financial Measures tables in this press release. These accompanying tables include details on the GAAP financial measures that are most directly comparable to non-GAAP financial measures and the related reconciliations between these financial measures. With respect to the Company’s non-GAAP guidance for the third fiscal quarter of 2014 and the fiscal year ending January 31, 2015, the Company is not able to provide a reconciliation of the non-GAAP financial measures to GAAP because it does not provide specific guidance for the various non-recurring and recurring reconciling items such as non-cash and other one-time compensation, one-time income tax expense (benefit), and legal claim related expenses, among others. Certain items that impact these measures have not yet occurred, are out of the Company’s control and/or cannot be reasonably predicted, and as a result, reconciliation of the non-GAAP guidance measures to GAAP is not available without unreasonable effort.
