Later history
These two businesses came under the common ownership of Bibag Bauindustrie Beteiligungs Aktiengesellschaft (subsequently renamed Strabag SE) – a company listed on the Vienna Stock Exchange – in 1998.[4] In 1999, Strabag acquired Strabag. In the same year, the company was delisted from the Vienna Stock exchange.[4]
In 2000, the holding company Bauholding Strabag (or Strabag SE since 2006) started a strong brand strategy throughout Europe, unifying all under the core brand "Strabag". In Austria Ilbau and Stuag merged into the new Strabag AG. The following year, the holding company became the major shareholder in German company Strabag AG, based in Cologne.[4]
Subsequent acquisitions included Deutsche Asphalt GmbH[7] in 2002, Walter Bau Group in 2005, a majority stake in Ed. Züblin in 2005, Adanti SpA, KIRCHNER Holding GmbH, F. Kirchhoff AG and Deutsche Telekom Immobilien und Service GmbH in 2008.[4]
In 2007, Strabag SE launched its initial public offering on the Vienna Stock Exchange.[4]
In December 2013 the Supreme Court of the Slovak Republic confirmed that one of Strabag's subsidiaries participated in bid rigging cartel of construction companies (together with companies of Skanska and Mota-Engil) in 2004. Illegal conduct was associated with the tender for the execution of works for the construction of the D1 highway from Mengusovce to Jánovce in Eastern Slovakia.[8]
In May 2022, Thomas Bull, a director appointed by the third largest shareholder, Rasperia Trading, which is owned by Russian entrepreneur Oleg Deripaska, was removed from the board to ensure compliance with the EU sanctions against Deripaska.[9]
In October 2024, Strabag sold its 6% shareholding in GySEV to the Government of Hungary.[10][11]
