Merger Cleared

Driving E.ON’s Acquisition of Innogy Assets from RWE in Germany’s Largest Energy Transaction

How do you remove competition concerns and set the stage for transformational growth?

In March 2018, German energy company E.ON, one of the world’s largest electric utility providers, announced that it would acquire the distribution and consumer solutions business as well as some electricity generation assets of Innogy from its controlling shareholder and Germany’s second-largest utilities company, RWE.

The €43 billion acquisition was part of an extensive asset swap transaction between E.ON and RWE. The European Commission (“EC”) announced an in-depth merger investigation into the transaction in March 2019, citing concerns that the combined entity would lessen competition in retail markets for electricity and gas in some member states.

Our Impact

Europe’s largest energy transaction to date was completed in 2020, positioning E.ON as a major energy operator, with more than 50 million customers in 15 countries.
