Linked Reviews
Financial and corporate
Founded in 1921, CERHA HEMPEL is among Austria’s 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 

Advised AT&S on a USD250 million sustainability linked loan from the International Finance Corporation, alongside a USD150 million facility from Maybank, to support the development of its semiconductor manufacturing facility in Malaysia. The financing is notable for its sustainability linked structure and its role in supporting advanced semiconductor production for high-performance computing and AI applications.

The firm also advised OMV on the establishment of Borouge Group International, a new global polyolefins group formed through the combination of Borealis and Borouge and the acquisition of NOVA Chemicals. Valued at over USD60 billion, the transaction is notable for creating one of the world’s largest polyolefins producers and involved complex cross border structuring, corporate and regulatory advise across multiple jurisdictions.
