Adler Pelzer Group announces the successful closing of the acquisition of 73,25% shares of the listed company STS Group

Adler Pelzer Group (“APG”) announces the successful closing of the acquisition of 73,25% shares of the listed company STS Group from its main shareholder Mutares after all antitrust clearances and other conditions have been cleared. APG, as buyer of the controlling stake, decided already to make a Voluntary Trade Offer according to Section 10 §1 and 3 in conjunction with Section 29 §1 and Section 34 of the of the German Securities Acquisition and Takeover Act (Wertpapiererwerbs- und Übernahmegesetz – “WpÜG”).

This business which provides Plastics Solutions to “Hard Trim” is mainly located in Europe, China and Mexico, with a development opportunity in the USA. It has already achieved a turn-over of 235M€ in 2020. The products, body and structural parts made of plastics and composites, painted or not, are delivered as single parts or as subassemblies today mainly to Heavy Truck OEMs, and growingly to Car OEMs, as the technology and the processes are well adapted to smaller series like New Energy Vehicles.

The added Plastics Division will benefit from the existing presence of APG with sales teams in contact with many customers, of local operations and administration teams, of an established network of suppliers for materials and services. Synergies in automotive market understanding and strategy, in Global Customer management, in all central functions including knowledge of process efficiency (Press Moulding, Injection Moulding) and raw material purchasing (Polyolefins and Glass Fibre), as well as in other corporate functions, will allow to derive value for the market.

 “The Adler Pelzer Group takes a further step for growth with the integration of Hard Trim to be combined with our competence in Soft Trim and Acoustics, adding a complementary product range to our Group in the automotive market of Light Vehicles, Vans and Heavy Truck” commented Pietro Lardini, CEO of Adler Pelzer Group.
