American giant acquires company with a transformer plant in Pravets GE Vernova, a provider of energy equipment and services that spun off from the American industrial giant General Electric, has reached an agreement to acquire the German high-voltage equipment manufacturer Trench Group. The deal is valued at $9 billion and will significantly expand the American company's portfolio. The German-based Trench Group has been active in Bulgaria since 2006 through its plant in Pravets, located near Sofia. The Bulgarian entity, "Trench Bulgaria," serves as a vital internal supply unit for the group and employs approximately 250 people. The Pravets plant primarily manufactures components for high-voltage transformers. Its entire output is exported to other company facilities in countries such as Germany, Italy, and Canada, where the components are incorporated into final products. The German group plans to expand its operations in Bulgaria by constructing a new plant in the Botevgrad area. This investment is estimated at ˆ20 million and is expected to create approximately 400 new jobs in the region. The acquisition of Trench Group by GE Vernova is expected to be finalized in the second half of 2027, subject to obtaining all necessary regulatory approvals. The transaction will be financed through an equal mix of cash on hand and debt. With a history spanning over 130 years, Trench Group is a key supplier to more than 800 utility companies and major infrastructure operators worldwide. The company specializes in the production of high- and medium-voltage bushings, instrument transformers, and reactors. In 2023, the company was spun off from the German giant Siemens Energy and subsequently sold to the investment fund Triton. Over the past two years, the Trench Group has reported stable financial results, with annual revenues exceeding ˆ1 billion.
