Key Events Affecting Business Performance

Acquisitions and Investments

WACKER bolstered its silicone business in China in 2022 and acquired a 60-percent stake in specialty silane manufacturer SICO Performance Material (Shandong) Co., Ltd. Organofunctional silanes are important ingredients in high-performance adhesives and sealants, as well as in coatings and composites. The transaction was completed in early May 2022 after the necessary regulatory and antitrust approvals were granted. WACKER paid around €170 million to cover the purchase price and a proportionate share of the company’s working capital.


The Federal Ministry for Economic Affairs and Climate Action did not issue the foreign trade clearance required for the merger of Siltronic AG with GlobalWafers Co., Ltd. by the deadline for the close of the transaction on January 31, 2022. As a result, the planned merger did not materialize. Consequently, the irrevocable undertaking signed by WACKER and GlobalWafers was void. Under this agreement, WACKER had undertaken to sell its 30.83-percent stake in Siltronic to GlobalWafers. As a result, WACKER no longer recognized this investment as assets held for sale, but once again as an equity-accounted investment.

Capital Expenditures

As planned, capital expenditures increased markedly year over year, coming in at €546.8 million (2021: €343.8 million). Spending was focused on expanding capacity at all four business divisions and included increasing liquid silicone rubber capacity at our sites in Burghausen (Germany) and Adrian, Michigan (USA). In India, facilities for high-temperature vulcanizing solid silicone rubber came on stream at the new Panagarh site. We are expanding our capacities in Nanjing, China, with a new reactor for dispersions and a spray dryer for dispersible polymer powders. We are transforming our site in Halle (Germany) into a competence center for mRNA actives, while a new biotech research facility is being built at our Corporate R&D Center in Munich (Germany). At our fully integrated sites of Burghausen and Nünchritz in Germany, we also invested in several projects for intermediates used in the manufacture of specialty silicones, as well as in facilities to produce hyperpure polysilicon.

Dispersible Polymer Powders
Created by drying dispersions in spray or disc dryers. VINNAPAS® polymer powders are recommended as binders in the construction industry, e.g. for tile adhesives, self-leveling compounds and repair mortars. They improve adhesion, cohesion, flexibility and flexural strength, as well as water-retention and processing properties.
Binary system in which one solid component is finely dispersed in another. VINNAPAS® dispersions are vinyl-acetate-based copolymers and terpolymers in liquid form. They are mainly used as binders in the construction industry, e.g. for grouts, plasters and primers.
Hyperpure polycrystalline silicon from WACKER POLYSILICON is used for manufacturing wafers for the electronics and solar industries. To produce it, metallurgical-grade silicon is converted into liquid trichlorosilane, highly distilled and deposited in hyperpure form at 1,000 °C.
Silanes are used as monomers for the synthesis of siloxanes or sold directly as reagents or raw materials. Typical applications include surface treatment, agents (medically active substances) in pharmaceutical synthesis, and coupling agents for coatings.
General term used to describe compounds of organic molecules and silicon. According to their areas of application, silicones can be classified as fluids, resins or rubber grades. Silicones are characterized by a myriad of outstanding properties. Typical areas of application include construction, the electrical and electronics industries, shipping and transportation, textiles and paper coatings.
