Private‑equity firm Platinum Equity signed a deal to acquire Tangent Technologies, an Aurora, Illinois manufacturer of synthetic lumber and related composites. Founded in 2003, Tangent’s catalog spans lumber, sheet and structural solutions for decking, docks, fencing and broader infrastructure projects. The Sterling Group will divest the business pending customary regulatory approvals.

CEO Kevin Potthoff, who oversees Tangent’s product lines, said the partnership will give the company access to Platinum Equity’s capital and operational expertise. The transaction is slated to close in the third quarter of 2026, matching the buyer’s push to deepen its footprint in engineered‑materials and capture growth from rising construction spending.

Analysts view the deal as a consolidation that could tighten supply chains for construction‑grade composites, a segment benefiting from heightened infrastructure budgets. Platinum Equity’s history of scaling niche manufacturers suggests Tangent may broaden its distribution network, accelerate R&D and launch new product lines, which should lift operating margins and create cross‑selling opportunities across the firm’s existing portfolio.

The acquisition adds a revenue stream estimated in the low‑hundreds of millions, though the exact price was not disclosed. With the deal set to finalize in 2026, Tangent will operate under Platinum Equity’s ownership while retaining its management team, positioning the company to meet expanding demand for durable, low‑maintenance building materials.
