Austria > Capital markets

Managing partner Clemens Hasenauer now solely heads the team at Cerha Hempel. His specialism in M&A and corporate law serves as a reflection of the team’s expertise in this intersection spanning a wide range of debt and equity transactions with much of its recent work falling into the DCM space. Volker Glas is a key contact for this and has recently led on a number of bond placements, including green bonds. Other regular instructions stem from financial services providers requiring assistance with the update of debt issuance programmes and with regulatory matters. The latter are typically led by Peter Knobl, while senior counsel Christian Aichinger provides wide-ranging capital markets, finance and corporate support.
