WATERWORKS TO JOIN RH CREATING THE FIRST FULLY INTEGRATED LUXURY HOME PLATFORM IN THE WORLD

Danbury, Conn. and Corte Madera, Calif.—April 12, 2016—Waterworks, the premier luxury bath and kitchen brand founded in 1978 by Barbara and Robert Sallick, and now led by Chief Executive Officer Peter Sallick since 1993, today announced it has chosen to join forces with RH—creating the first fully integrated luxury home platform in the world—offering a complete collection for every room of the home, in every channel, to both design professionals and consumers. Peter Sallick and Ralph Bennett, President, will continue to lead the Waterworks brand independently along with the rest of the leadership team from their headquarters in Danbury, Connecticut.

Waterworks has long been the definition of the well-appointed bath, and is the only complete bath and kitchen business offering fittings, fixtures, furniture, furnishings, accessories, lighting, hardware and surfaces under one brand in the market. Waterworks is comprised of the Waterworks, Waterworks Kitchen and Waterworks Studio brands, all built on a foundation of impeccable style, design integrity, quality and craftsmanship. Waterworks products are sold through its 15 showrooms in the U.S. and U.K., as well as its boutique retail partners, hospitality division and online. The Company prides itself on its deep relationships in the design community and the technical expertise and tenure of its people.

Peter Sallick, Waterworks Chief Executive Officer commented, “We enter this new partnership with a great sense of excitement and pride. We have come to know RH, led by its Chairman and Chief Executive Officer, Gary Friedman, as a special company with both the scale to make a difference and the high touch and creative leadership to see the world at a personal level. We’ve admired RH for their unique partnerships with designers and artisans from around the globe, their ability to reimagine the retail experience through the adaptive reuse of historic and architecturally iconic buildings, and for the passion and innovation they bring to our market.”

Mr. Sallick continued, “We believe the combined capabilities of our two organizations creates an opportunity to amplify the authentic and special brand we have built and accelerate the pursuit of our vision to build the most innovative and inspirational bath and kitchen brand in the world. Together, we will create a dramatic path toward long term growth and value for our brand, people, customers and suppliers.”

Barbara Sallick, Waterworks co-founder and Senior Vice President of Design stated, “We look forward to our partnership with RH founded upon our mutual respect for great design, artisanal craftsmanship and product innovation. Together with the RH team, whose creativity and market leadership are inspiring, we expect to grow the Waterworks brand in the luxury space while continuing to provide exemplary service to our clients. Robert and I founded Waterworks 38 years ago following in the footsteps of my entrepreneurial father who opened a plumbing supply business in Danbury, Connecticut in 1925. With RH at our side, we anticipate the rewarding adventure of building our company for many generations to come.”

Ralph Bennett, Waterworks President added, “We believe RH is the most significant brand being built in the home market today, creating extraordinary opportunities for us to collaborate and benefit from their unique and growing platform. As a combined organization, we look forward to extending and expanding our passion, product offer and commitment to outstanding service to our incredibly valuable clients.”

Gary Friedman, RH Chairman and Chief Executive Officer commented, “There are certain brands that define their categories, like Hermès, Tiffany, Apple, Range Rover and Ralph Lauren, and we believe that Waterworks is one such brand. We have long held great admiration and respect for the esteemed brand and business the Sallicks have built, and feel honored and privileged to be partnering with the entire Waterworks team, as we combine forces to further redefine the industry.”

Mr. Friedman concluded, “We are thrilled to add this prestigious brand to our product platform, as it not only positions RH as an authority in two of the most important rooms of the home—the bath and kitchen—but also creates the first fully integrated luxury home platform in the world. There are very few opportunities to partner with a well-managed, growing, double-digit EBITDA margin brand such as Waterworks. This partnership represents a key opportunity to drive long-term growth and value creation for our shareholders.”

The transaction is valued at approximately $117 million, which is subject to changes in working capital and other adjustments, and will be funded from RH’s existing cash balances. Subject to customary closing conditions, the transaction is expected to close during the second quarter of fiscal 2016 and until that time the two businesses will continue to operate as separate entities. Upon completion of the transaction, Waterworks is expected to be accretive to RH’s fiscal 2016 earnings. RH will provide additional information to investors concerning the anticipated financial impact of the transaction when the Company reports first quarter fiscal 2016 financial results.

In connection with the transaction, Peter Sallick and Ralph Bennett have agreed to invest in continuing equity interests in the Waterworks business, which creates additional incentives for management to continue to drive growth and profitability of the business in future periods.
