Overview
CA Immo, formally CA Immobilien Anlagen AG, is an Austrian real estate company headquartered in Vienna. Its principal business is the development, ownership, management and investment of office properties in core Central European markets, especially Germany, Austria and selected countries in Central and Eastern Europe. The company operates through offices in Vienna, Berlin, Frankfurt, Munich, Warsaw, Budapest and Prague, supporting a regional platform centered on commercial real estate. The company was established in 1987 within Creditanstalt-Bankverein, an Austrian commercial bank, and became publicly listed on the Vienna Stock Exchange in 1988. Its shares entered the exchange's Prime Market in April 2007. CA Immo was included in the Austrian Traded Index, or ATX, in March 2011, reflecting its position among the larger companies traded in Vienna at that time. CA Immo's business model combines the management of existing income-producing properties with the development of new office buildings. Germany became particularly important after the 2008 acquisition of Vivico Real Estate GmbH from Deutsche Bahn. The transaction brought CA Immo a substantial portfolio of non-operational land and brownfield sites, as well as established operations in Berlin, Frankfurt and Munich. It also strengthened the company's role as an office developer in Germany, where urban redevelopment and large-scale commercial projects became a major part of its activities. The company expanded further into Eastern Europe at the beginning of 2011 through the acquisition of the property subsidiary of Österreichische Volksbanken Gruppe. This transaction broadened CA Immo's portfolio and operational footprint in markets including Poland, Hungary and the Czech Republic. Over time, the company has concentrated its activities on core locations and office properties rather than presenting itself as a broad, consumer-facing real estate conglomerate. CA Immo has also been involved in several attempted combinations with Immofinanz, another Austrian listed property company. Merger discussions failed in 2014, and a CA Immo takeover bid in 2015 did not succeed. After CA Immo's then-major shareholder O1 Group sold its approximately 26 percent holding to Immofinanz in 2016, Immofinanz itself later sold that stake to Starwood at the end of September 2018 after its own combination plan failed. Starwood-managed SOF-11 Klimt CAI subsequently became CA Immo's largest shareholder. Management responsibility is currently divided between Chief Executive Officer Keegan Viscius and Chief Financial Officer Andreas Schillhofer. Viscius oversees investment and asset management, development, corporate communications and sustainability, market research and data analysis, administration and information technology. Schillhofer is responsible for finance, accounting and taxes, controlling, financing, valuation, capital markets and investor relations, compliance, organization and legal matters. As of the supplied company information, CA Immo employed approximately 240 people across Austria, Germany and Eastern Europe at the end of 2025. Its positioning is that of a specialized, regionally focused office property developer and asset manager rather than a mass-market property brand.
History
CA Immo was founded in 1987 as part of Creditanstalt-Bankverein, an Austrian commercial bank. The company's original institutional setting helped establish it as a property investment vehicle rather than as a consumer-oriented real estate brand. It was listed on the Vienna Stock Exchange in 1988 and later moved its shares to the exchange's Prime Market in April 2007. The company's development accelerated through geographic expansion. In 2008, CA Immo acquired Vivico Real Estate GmbH, a Deutsche Bahn subsidiary. Vivico brought a portfolio of non-operational land and brownfield sites as well as operating locations in Berlin, Frankfurt and Munich. The transaction materially strengthened CA Immo's German presence and supported its strategy of developing office properties in major urban markets. Germany subsequently became one of the company's central operating platforms and a major focus for new office development. At the beginning of 2011, CA Immo acquired the property subsidiary of Österreichische Volksbanken Gruppe. This broadened its exposure to Central and Eastern Europe and added to its regional platform in countries such as Poland, Hungary and the Czech Republic. In March 2011, CA Immo became a member of Austria's ATX index, which tracks major companies traded on the Vienna Stock Exchange. CA Immo's operating model combines ownership and management of existing office properties with the development and realization of new projects. Its focus is on core Central European markets and commercial assets, especially office buildings. The company maintains offices in Vienna, Berlin, Frankfurt, Munich and the capitals of Poland, Hungary and the Czech Republic. Rather than operating as a diversified property-services retailer, it has positioned itself as a specialized developer and manager of institutional-quality office real estate. The company has been connected to a long-running series of proposed transactions involving Immofinanz. Merger negotiations in 2014 did not produce an agreement. A CA Immo takeover bid launched in spring 2015 also failed. In August 2016, O1 Group, then CA Immo's core shareholder and a group associated with Boris Mints and Dmitry Mints, sold its approximately 26 percent stake to Immofinanz. Immofinanz sought a combination of the two businesses, but that plan did not succeed. Immofinanz ultimately sold its CA Immo stake to Starwood at the end of September 2018. The Starwood-related ownership structure remained significant thereafter. The company's largest shareholder is identified as SOF-11 Klimt CAI S.à r.l., a Luxembourg entity managed by Starwood Capital Group. The remaining shares are held in free float or by CA Immo as treasury shares, according to the supplied company information. Leadership has evolved alongside the company's investment and development strategy. Keegan Viscius joined the Management Board as chief investment officer in November 2018 and became chief executive officer in June 2023. Andreas Schillhofer joined the Management Board as chief financial officer in June 2019. Together they share responsibility for corporate strategy, risk management, internal audit and human resources, while holding distinct investment, development, finance and corporate-governance portfolios. The supplied information states that CA Immo employed about 240 people across Austria, Germany and Eastern Europe at the end of 2025.
