Career

Krystian Czerniecki has a long track record of advising on landmark capital markets transactions in Germany. In the years prior to the entry into force of the EU Prospective Directive, he advised on numerous SEC-registered IPOs, rights offerings and listings of German issuers, transactions which helped to shape the modern German capital markets. He led the S&C team advising on the first IPO prospectus to be approved in Germany under the Prospectus Directive and, since then, has advised on dozens of offerings under this regime.

Today, Mr. Czerniecki’s capital markets practice is focused on IPOs, rights offerings, and investment grade, hybrid and high-yield debt offerings by non-U.S. issuers. Since 2000, he has advised on 21 of the top 27 IPOs and some of the most significant rights offerings in Germany as well as on numerous IPOs and rights offerings in France, Switzerland and Austria.

Mr. Czerniecki has represented issuers in a broad range of industries, but has particular expertise advising start-ups in the technology space, from e-commerce to biotech.

In recent years, there has been a resurgence in SEC-registered IPOs by European-based issuers and Mr. Czerniecki has been at the forefront of this development, advising numerous issuers, including SPACs, on NYSE and Nasdaq listings. Mr. Czerniecki’s practice combines decades of experience advising on SEC-registered offerings with a track record on tech-sector IPOs that is second to none.

In addition to his capital markets practice, Mr. Czerniecki also has deep experience advising on mergers and acquisitions, including cross border tender offers and going private transactions, as well as on business combinations involving U.S. and European listed SPACs.
