Implenia AG
The shares of Zschokke and Batigroup were delisted from the SIX Swiss Exchange after close of trading on 3 March 2006. The merger was completed by exchanging shares for the new Implenia shares, the value ratio being set at 65 (Zschokke) to 35 (Batigroup). The first trading day of Implenia shares on the Swiss stock exchange was 6 March 2006.[4]
In 2010, Implenia had acquired the Norwegian Betonmast Anlegg, a Norwegian infrastructure specialist.[12] Since March 2015, the German Bilfinger Construction (now renamed Implenia Construction) with activities in Germany, Austria and Sweden has also been part of the Group.[13] The acquisition of Bilfinger Hochbau followed in 2016.[14]
On 27 October 2020, Implenia announced an accelerated restructuring starting in 2021, marking a break with the construction group's years-long push for internationalization, which it declared over.[15] Its stock market value halved over the past two years, largely due to previous project acquisitions and purchases (such as in Sweden between 2015 and 2017). The company withdrew from unprofitable business areas in some markets (Sweden, Norway and Romania) and has since focused largely on Switzerland and Germany. Here, Implenia is active as a real estate developer and manager, as well as in building construction, civil engineering and specialist businesses such as timber construction and facade technology.[9] In the rest of Europe, the focus is largely on tunnel construction, as in Austria, France, Sweden, Norway and Italy.[16] As part of this accelerated restructuring, Implenia announced plans to lay off around 750 people and cut 2000 full-time positions by 2023. This transformation was completed ahead of schedule.[15][17]
In May 2021, Implenia completed the acquisition of BAM Swiss AG, a healthcare construction services provider in Switzerland headquartered in Basel.[18] With this acquisition, Implenia took over BAM Swiss AG's current projects such as the planning and realization of the Aarau Cantonal Hospital, the BSSE in Basel – a modern laboratory and research building for biosystems science and engineering – as well as the Felix Platter Hospital project in Basel and an ETH student residence in Zurich.[19][20]
Implenia acquired the leading Swiss real estate service provider Wincasa in May 2023.[21]
