Exhibit 99.1

RESTORATION HARDWARE HOLDINGS, INC. ANNOUNCES PRICING OF

$250 MILLION CONVERTIBLE NOTES OFFERING

Corte Madera, CA – June 18, 2015 – Restoration Hardware Holdings, Inc. (NYSE: RH) today announced the pricing of $250 million of 0% convertible senior notes due 2020 at a 25% conversion premium to yesterday’s closing stock price of $94.50. Restoration Hardware also granted the initial purchasers of the notes a 13-day option to purchase up to an additional $50 million of the notes on the same terms and conditions, for a total potential offering size of up to $300 million.

The Company has entered into convertible note hedge and warrant transactions on terms that have the effect of limiting earnings dilution as a result of the convertible notes issuance up to a 100% premium to today’s closing stock price. Under the terms of these transactions, the Company’s shareholders are not expected to experience earnings dilution until the Company’s stock price is above approximately $189, which corresponds to a market capitalization in excess of $7.9 billion based on the current diluted shares outstanding.

The Company intends to use this additional capital to fund its business initiatives including the expansion of its business and the pursuit of additional growth opportunities. The immediate use of a portion of the proceeds from the offering will be to pay the net cost for the convertible note hedge transactions.

The sale of the notes to the initial purchasers is expected to settle on June 23, 2015, subject to customary closing conditions.

The notes will not bear interest and will mature on July 15, 2020, unless earlier purchased by us or converted. The initial conversion rate is 8.4656 shares of common stock per $1,000 principal amount of notes, which is equivalent to an initial conversion price of approximately $118.13 per share representing a premium of 25% over yesterday’s closing stock price. The notes will be convertible into cash, shares of Restoration Hardware’s common stock, or a combination thereof, at Restoration Hardware’s election.

This press release does not constitute an offer to sell or the solicitation of an offer to buy, nor shall there be any sale of these securities in any state or jurisdiction in which such offer, solicitation, or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction. The notes and the shares of common stock issuable upon conversion of the notes, if any, will not be registered under the Securities Act of 1933, as amended (the “Act”) or any state securities laws, and unless so registered, may not be offered or sold in the United States except pursuant to an exemption from the registration requirements of the Act and applicable state laws.
