Wolf Theiss

Wolf Theiss is an Austrian-based corporate law firm founded in 1957 with a focus on Central and Eastern Europe. The firm provides cross-border legal services to multinational corporations, financial institutions, private equity firms, and state-owned enterprises across markets such as Austria, Czech Republic, Slovakia and Slovenia. Its work spans mergers and acquisitions, project finance, international arbitration and cross-border litigation involving clients from industries including energy, telecommunications, banking, transportation, and real estate.

History

Founded in Vienna during the post-World War II era, the firm expanded its footprint in the late 20th century alongside economic liberalization in Central Europe, the collapse of the Soviet Union, and the enlargement of the European Union. Early engagements linked the firm to privatization projects in the Czech Republic, Slovakia, and Poland and transactional work involving European Bank for Reconstruction and Development, International Finance Corporation, and regional development banks. During the 1990s and 2000s the firm opened offices in capitals including Prague, Budapest, Bucharest, and Belgrade, responding to demand from Siemens, General Electric, E.ON, Shell, Raiffeisen Bank International, and UniCredit. Its growth mirrored regional trends such as accession negotiations with the European Union and investment flows tied to the European Investment Bank.
