Corte Madera, CA – June 11, 2015 – RH (Restoration Hardware Holdings, Inc. - NYSE:RH) today announced record financial results for the first quarter ended May 2, 2015. The Company will also post a video presentation highlighting its continued evolution, recent performance, and the announcement of a new business on the RH Investor Relations website at ir.restorationhardware.com.

First Quarter Highlights

Gary Friedman, Chairman and Chief Executive Officer, commented, “RH continues to outperform the home furnishings industry by a wide margin. Net revenues exceeded our outlook and increased 15% on top of a 22% increase last year. Comparable brand revenues increased 15% on top of 18% last year – representing a 33% increase over the two year period. Additionally, we grew our adjusted operating margin by 60 basis points and adjusted net income by 38%, both ahead of our expectations, and further demonstrating the disruptive nature of the RH brand and the power of our multi-channel business model.”

Mr. Friedman continued, “Our first next generation Design Gallery, RH Atlanta - The Gallery at the Estate in Buckhead - continues to accelerate and gain momentum and we are even more pleased with its evolution. With the 2015 Source Books just now reaching the Atlanta market, as well as the addition of our new businesses later this year, we believe that this gallery is well on track to exceed our original expectations.”

Mr. Friedman added, “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. Later this year, we will be opening next generation Design Galleries in Chicago, Tampa, Denver and Austin. Looking to 2016 and beyond, we now have signed leases for 10 next generation Design Galleries and are in

negotiations or have sites identified for at least 25 additional locations. In addition, we have multiple new concepts and services in our product development pipeline that we believe will continue to demonstrate the innovative and disruptive nature of our brand, and drive industry leading performance for years to come.”

Mr. Friedman concluded, “The business momentum we are experiencing thus far in 2015, coupled with the launch of new businesses and the opening of four next generation Design Galleries later this year, gives us further confidence in our financial outlook for fiscal 2015. We are increasing our adjusted net income guidance for fiscal 2015 to growth in the range of 30% to 36% - above our long term target of mid to high twenties - and now expect net revenues to grow in the range of 15% to 17%. Fiscal 2015 is a bridge year for RH, with revenue growth targeted in the mid-teens, and then reaccelerating to our long term goal of 20% as our real estate transformation and new product introductions ramp in fiscal 2016. While still in the early stages of building RH into the leading home brand for the luxury customer, we are well on track towards our long-term goal of $4 billion to $5 billion in North American sales, mid-teens operating margins, significant free cash flow and industry-leading return on invested capital.”

**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, 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 non-GAAP financial measures, including similarly titled measures, 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 second quarter of fiscal 2015 and the fiscal year ending January 30, 2016, 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. For previous periods, such non-recurring and recurring reconciling items included non-cash and other one-time compensation expense, 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.
