Founded in 1921,CERHA HEMPELis among Austrias largest and leading firms. Since the late twentieth century, the firm has been growing a network of offices in Eastern Europe that now encompasses branches in Belarus, Bulgaria, Czech Republic, Hungary, Romania and the Slovak Republic.

The firm has a strong focus on all corporate and commercial matters with especial strength in capital markets regularly representing leading listed Austrian companies and issuers. 

 

Highlights 

In capital markets, the firm advised listed company, voestalpine AG, on its successfully issue of its first green corporate bond for EUR 500 million with a term of five years and a coupon of 3.75%. This transaction is notably innovative as the first Green bond in the European Steel industry. 

In M&A, the firm played a role advising OMV in the high profile strategic acquisition by ADNOC of Mubadala's interest in OMV. The acquisition, valued at $4.1 billion, is one of the largest M&A deals in the Austrian market.

The firm's professionals combine legal expertise with a strong awareness of commercial and strategic considerations, ensuring practical and business-focused advice. The public law team – especially Hans Kristoferitsch, Stefan Huber, and Claudia Hanslik-Schneider– impresses with its deep legal knowledge, strategic foresight, and comprehensive understanding of both national and EU legal frameworks. What I particularly appreciate about the team is their combination of legal excellence and practical insight.
