Nexia expands in Mannheim

Nexia GmbH, one of the leading medium-sized auditing and tax consulting companies in Germany, is acquiring DELTA Revision GmbH, thereby expanding its Mannheim location.

Effective 1 September 2025, DELTA Revision GmbH will join Nexia GmbH. The three managing partners of DELTA Revision GmbH, Klaus Bertram, Jeffrey Larson and Alexander Spieß, will strengthen Nexia GmbH's Mannheim location with around 20 employees. Nexia, which already has a location in Mannheim, is thus strengthening its presence in the Rhine-Neckar region. With a turnover of around 70 million euros, Nexia is one of the leading medium-sized auditing and tax consulting companies in Germany. Nexia operates worldwide through its international Nexia network with more than 22,000 employees in over 120 countries.

The DELTA Group is active in the traditional areas of auditing and tax consulting and thus represents an ideal professional and regional complement to the existing range of services offered by Nexia GmbH.

"As a native of Heidelberg who studied at the University of Mannheim, I know the region very well. The addition of DELTA Revision is an important step for us in strengthening our presence in the Rhine-Neckar region. With the three former managing partners of DELTA Revision, we are gaining outstanding experts who are also well known and well connected in the Rhine-Neckar region. In addition, we are very much looking forward to welcoming 20 additional highly qualified employees who will enrich our team," says Santosh Varughese, spokesperson for Nexia GmbH, explaining the acquisition of the DELTA Group.

"By merging with Nexia, our clients will benefit from an even broader range of services and expertise in the future. Nexia aims to be the number one auditor and advisor, especially for globally oriented German SMEs. The Rhine-Neckar region as a whole will benefit from this," adds Klaus Bertram, co-founder of DELTA Revision.

Alexander Spieß, also co-founder of DELTA Revision, is equally enthusiastic about the merger with Nexia: ‘As a partner-led company, Nexia offers solution-oriented services, individual advice from a single source and direct decision-making processes, just like us. Complex issues are resolved by interdisciplinary teams led by the partners responsible for the mandate.’ Jeffrey Larson adds: ‘With this step, we are positioning ourselves for the future, both for our clients and for our employees.’

Matt Howell, Chief Executive Officer of Nexia International, is convinced: ‘I am delighted to welcome the new partners and employees to our network. This will further strengthen our position in the Rhine-Main-Neckar region, especially for internationally active medium-sized companies.’
