Solo Brands Acquires TerraFlame

Acquisition will enable Solo Brands to bring the fire burning experience indoors

GRAPEVINE, Texas – May 11, 2023 – Solo Brands, Inc (NYSE: DTC), (“Solo Brands” or the “Company”), a direct-to-consumer (DTC) platform for rapidly growing lifestyle brands including Solo Stove, Chubbies, Oru Kayak, and ISLE, today announced it has acquired TerraFlame, a company founded with the mission of creating warm, inviting and ambient spaces around clean burning flame.

“We are pleased to welcome TerraFlame to the Solo Brands family and thankful to Gerald Berger, Oleg Berger and Lenny Vainberg for choosing us as the right long-term partner for them,” said John Merris, CEO of Solo Brands. “This strategic acquisition complements our brands, and alongside Solo Stove, allows us to offer our customers the fire burning experience outdoors, and with the addition of TerraFlame, we’re thrilled to bring the fire inside. We hope to leverage our direct-to-consumer and wholesale expertise to support TerraFlame’s growth while also leaning into TerraFlame’s shared passion for product innovation and incredible products to elevate the Solo Brands customer experience.”

The announcement comes on the heels of Solo Brands’ continued business momentum, driven by product innovation, focus on the customer experience, wholesale and retail penetration, and international expansion. The Company launched 15 new products in 2022, including the Solo Stove table top fire pit Mesa and Pi pizza oven. On the wholesale front, Solo Brands is now offering its products through key strategic retail partners including Costco, Dick’s Sporting Goods, Ace, Academy, Scheel’s, and others.

TerraFlame creates warm and inviting places where customers can roast s’mores, and gather with friends and loved ones. It combines eco-friendly and sustainable fireplaces fuels with artisan crafted fire features that showcase flame in its truest form. The company sells a range of indoor fire products, including its S’mores By TerraFlame^® portable tabletop s’mores roaster designed to be used indoors, while still providing the sound of campfire memories. In addition to its e-commerce platform, TerraFlame has a robust retail network including Target, Pottery Barn, William-Sonoma, and Crate & Barrel.

TerraFlame’s team – including its CEO Lenny Vainberg, who will be appointed the role of TerraFlame General Manager – will become a part of the Solo Brands team.

“We are thrilled to join the Solo Brands team and to have found a partner that supports our vision for TerraFlame,” said Vainberg.
