HOUSTON, July 31, 2026 /PRNewswire/ -- The Sterling Group ("Sterling"), a middle market private equity firm, today announced it has completed the previously announced sale of Tangent Technologies ("Tangent") to Platinum Equity. Financial terms of the transaction were not disclosed.

Headquartered in Aurora, Illinois, Tangent is a leading manufacturer of high-performance synthetic materials used for outdoor living, site amenities, structural applications and marine decking. In recent years, these premium materials have become a leading substitute for traditional building materials given their durability, low maintenance, and aesthetics. Tangent manufactures its products using a combination of post-consumer and post-industrial recycled feedstock.

In 2018, Sterling partnered with Tangent's founders to build on the company's successful track record of innovation and exceptional customer service in the synthetic materials industry. Sterling's experience partnering with family sellers and history of sharing economics with employees were important factors in the partnership with Tangent. During Sterling's ownership, Tangent expanded to serve new customers and new end markets, more than tripling in size.

Moelis and Lincoln served as financial advisors and McDermott Will & Schulte served as legal advisor to Tangent.
