What Sts Group does

STS Group AG is a German-headquartered supplier of fiber-reinforced composite and plastic components for the global automotive industry. Founded in 2013 as a spin-off from Autoneum, the company produces lightweight parts using Sheet Molding Compound (SMC), injection molding, and thermocompression processes, serving commercial vehicle OEMs, light commercial vehicle producers, passenger car manufacturers, and luxury vehicle brands.

The company's product portfolio spans exterior and interior body components, aerodynamic and acoustic parts, battery covers for electric vehicles, and roof modules. Production is organized across 17 global sites in five countries (Germany, France, China, Mexico, and the United States), comprising 8 production plants, 4 logistics/service plants, and 3-4 R&D centers. The business operates on a tier-1 supplier model, monetizing through B2B component sales into OEM vehicle programs with annual production volumes up to 100,000 parts per part number.

STS Group generates revenue through long-term OEM supply contracts tied to multi-year vehicle platform programs. Following its 2013 spin-off from Autoneum, the company pursued an inorganic expansion strategy with three notable acquisitions (MecaplastGroup in 2016, Autoneum Brazil acoustic operations in 2017, and Plastic Omnium's global truck business in 2017) and greenfield entries in Poland (2015) and China (HQ 2018, plant 2019). Under Chairman Paolo Scudieri and CEO Alberto Buniato (appointed February 2022), STS reported it fulfilled its 2025 forecast with increased profitability while operating within the Adler Pelzer Group ownership structure.
