Argand Partners’ OASE Living Water Acquires the Söll Group

Argand Partners, the New York- and San Francisco Bay Area-based middle market buyout firm, today announced that Oase Living Water (“OASE”) has acquired the German-based Söll Group (“Söll”), a leading supplier of specialized water treatment products, water analysis and filtering technology, and premium fish food for consumer and commercial applications. Headquartered in Hörstel, Germany, OASE is the global market leader in water gardening products, offering a suite of products that enable the creation of tranquil, inviting outdoor oases, from simple to elaborate. The terms of the transaction were not disclosed.

The Söll Group has a 25-year history of developing and producing environmentally friendly and innovative premium water treatment products for end consumers and professional contractors. Söll designs systems for ecological maintenance of natural and man-made bodies of water and for the treatment of drinking water and waste water. The company also offers water analysis instrumentation for the management of water resources. Söll will benefit from OASE’s global distribution capability, which will expand the market for Söll’s innovative products internationally. Söll provides OASE with a leading research and development capability and product portfolio that significantly enhances OASE’s existing water treatments offering.

“Söll’s expertise is highly complementary to OASE’s current line of products and services,” said Thorsten Muck, CEO of OASE. “OASE’s customers, from hobbyists to expert users to commercial contractors, stand to greatly benefit from Söll’s solutions. The acquisition is an exciting milestone for OASE and promises to open up myriad business opportunities.”

“Partnering with OASE puts us in a position to introduce Söll’s extensive range of innovative, premium products and systems to an international market,” said Thomas Willuweit, Founder and Managing Director of Söll. “Together, we aim to offer the most comprehensive array of water treatment solutions to meet the varied needs of our end consumers and professional-use clients.”

“We are excited to support strategic growth consistent with OASE’s long-standing heritage of offering premium products underpinned by strong research and development and continuous innovation. The Söll acquisition is highly complementary to OASE’s existing business,” added Heather Faust, Partner and Managing Director of Argand Partners.
