ScottsMiracle-Gro Acquires Rhizoflora Assets to Further Bolster Hawthorne Gardening Portfolio; Announces Investment by The Hawthorne Collective

MARYSVILLE, Ohio, Aug. 16, 2021 (GLOBE NEWSWIRE) -- The Scotts Miracle-Gro Company (NYSE: SMG), the world’s leading marketer of branded consumer lawn and garden as well as indoor and hydroponic growing products, today announced that it has acquired Rhizoflora’s leading nutrients business including its Terpinator and Purpinator brands, further bolstering The Hawthorne Gardening Company product portfolio.

Separately, the Company announced that its subsidiary, The Hawthorne Collective, has purchased a warrant to buy equity in Dewey Scientific for $3.2 million, which will help advance Dewey’s industry-leading cannabis genomics and cultivation. The investment from the Hawthorne Collective will be used only for purposes permitted by applicable laws of the United States.

Hawthorne becomes primary provider of Rhizoflora’s Terpinator and Purpinator brands
Rhizoflora has been the producer of the industry-leading Terpinator and Purpinator brands. Prior to this acquisition, Hawthorne has been a distributor of the Rhizoflora brands. Now, Hawthorne is the primary provider of the Terpinator and Purpinator product lines in the United States.

“This acquisition reflects our broader strategy to build the most comprehensive portfolio of products and solutions to serve growers at an unparalleled scale,” said Chris Hagedorn, Hawthorne Gardening division president. “We appreciate our long-standing partnership with Rhizoflora and look forward to elevating the brands, including bringing Terpinator and Purpinator to expanded markets.”

The Rhizoflora acquisition follows the recent announcement of plans to acquire Hydro-Logic Purification Systems, Inc., a leading provider of products, accessories and systems for water filtration and purification, with a targeted closing of August 27.

Under the terms of the Rhizoflora deal, the Company will acquire substantially all the assets of Rhizoflora for $33.5 million, adding approximately $8 million in annualized sales. Acquiring the Terpinator and Purpinator brands will extend the Hawthorne Signature Nutrients portfolio into supplements that are being rapidly adopted as the industry standard to fully express plant characteristics. Hawthorne will increase marketing and sales efforts around the brands to support the Hawthorne 360 Total Solution for growers.

Hawthorne Collective investment expands R&D relationship with Dewey
