In 1990, it was re-organised as BHW Holding GmbH to become BHW Holding AG later, followed by an initial public offering in 1997. In March 2005, Deutsche Postbank announced that it has acquired a 9.2% stake in the company.[2] Later that year, Deutsche Postbank made public its intent to purchase more than 90% of BHW's shares[3] and made an offer to remaining shareholders.[4] The acquisition was completed in 2005.[5][1]
Until 2019, BHW Kreditservice GmbH took over the management of customers of other mortgage banks and building societies, such as Axa Bausparkasse and DSL Bank (so-called loan processing as an outsourcing service), in addition to servicing its own customers.[6]
DB Bauspar, which is part of the Deutsche Bank Group, sold home savings contracts under the BHW brand name from January 6, 2014 to December 31, 2015; in 2019, the two providers were merged under the BHW name.[7]
