Overview
S IMMO AG is an Austrian real estate investment company whose business is based on acquiring, developing, managing and investing in income-producing property. Its portfolio spans several major real estate categories, including office buildings, retail assets, residential properties and hotels. The company operates in Austria, Germany and a number of Central and Eastern European markets, namely Slovakia, Czechia, Hungary, Romania and Croatia. The company traces its origins to the launch of s Immobilien-Fonds Nr. 1, a real estate security introduced on the Vienna Stock Exchange on 19 October 1987. This instrument was the precursor of the present s-Immo-Invest participating certificate and represented the first real estate security listed on the Vienna Stock Exchange. S IMMO's corporate structure and share identity evolved over time. Sparkassen Immobilien Anlagen AG merged with Die Erste Immobilien AG in 2002. After a 1:20 capital split, Die Erste Immobilien Aktie became the S Immo share and began trading under a new identification number on 28 June 2002. S IMMO has remained a Vienna-listed real estate company. Its shares were included in the ATX, the benchmark index of the Vienna Stock Exchange, from September 2017 until November 2022. In November 2022, CPI Property Group S.A. announced that it held 88.37% of S IMMO's share capital, directly and indirectly through Immofinanz AG. This change significantly altered the company's ownership context and connected S IMMO more closely with CPI Property Group's broader real estate platform. The company's investment approach is diversified by both property type and geography. Office buildings form the largest part of its portfolio, supplemented by retail properties, residential assets and hotels. Its regional strategy combines exposure to established markets such as Austria and Germany with investments in Central and Eastern Europe. The portfolio is therefore oriented toward recurring rental income, occupancy management, asset value preservation and selective real estate investment rather than consumer-facing property development under multiple product brands. At the end of 2023, S IMMO reported 244 properties with approximately 1.5 million square metres of gross lettable area and property assets valued at EUR 3,477.6 million. Germany represented 15.7% of portfolio book value, Austria 22.0%, and Central and Eastern Europe 37.7%; the remaining share was attributable to other portfolio classifications or geographical reporting differences. By property type, offices accounted for 67.2% of the portfolio, retail for 19.4%, residential property for 6.1% and hotels for 7.3%. The overall occupancy rate was 90.6% and the reported total rental yield was 6.8% at that reporting date. These figures describe the investment portfolio rather than sales of branded consumer products. S IMMO's brand identity is consequently institutional and asset-oriented. It presents itself primarily as a listed property investment company rather than as a retail brand. Its stakeholders include shareholders, tenants, financing partners, property managers and institutional real estate investors. The company’s principal competitive proposition is a geographically diversified income-producing portfolio supported by long-term ownership and active management across several European markets.
History
S IMMO's history begins with the development of listed real estate investment instruments in Austria. On 19 October 1987, s Immobilien-Fonds Nr. 1 was launched on the Vienna Stock Exchange. It was described as the first real estate security listed on that exchange and became the predecessor of the s-Immo-Invest participating certificate. This event established the foundation for a publicly traded real estate investment business rather than a conventional property-development company. The corporate structure changed in 2002, when Sparkassen Immobilien Anlagen AG merged with Die Erste Immobilien AG. Following a 1:20 capital split, Die Erste Immobilien Aktie was converted into the S Immo share. The share began trading under a new identification number on 28 June 2002, marking the modern S IMMO identity in the Vienna market. The reorganisation linked the company's present corporate and securities history with its earlier real estate investment vehicles. S IMMO subsequently developed a geographically diversified portfolio across Austria, Germany and Central and Eastern Europe. Its investment universe expanded beyond a single property category, incorporating office buildings, retail properties, residential assets and hotels. This mix enabled the company to pursue rental income from multiple tenant and economic segments while maintaining exposure to several European markets, including Slovakia, Czechia, Hungary, Romania and Croatia. The company achieved a higher profile in Austria's capital market when its shares joined the ATX, the benchmark index of the Vienna Stock Exchange, in September 2017. S IMMO remained in the index until November 2022. Its index membership reflected the importance of listed real estate companies within the Austrian equity market, although index inclusion did not alter the company's underlying focus on property ownership and management. Ownership became a major strategic feature in 2022. On 21 November 2022, CPI Property Group S.A. announced that it held 88.37% of S IMMO's share capital, both directly and indirectly through Immofinanz AG. The announcement placed S IMMO within the ownership structure of one of Europe's larger property groups and reduced the relative importance of the company as a broadly dispersed standalone listed investment vehicle. By the end of 2023, S IMMO's portfolio comprised 244 properties with approximately 1.5 million square metres of gross lettable area and property assets valued at EUR 3,477.6 million. Germany accounted for 15.7% of portfolio book value, Austria for 22.0% and Central and Eastern Europe for 37.7%. In property-type terms, office buildings made up 67.2% of the portfolio, retail properties 19.4%, residential properties 6.1% and hotels 7.3%. The overall occupancy rate was 90.6%, while total rental yield was reported at 6.8%. S IMMO's present identity is therefore that of an Austrian-origin, European real estate investment company. Its history combines exchange-listed property securities, corporate consolidation, expansion across several European markets, capital-market visibility through ATX membership and a later transition into the majority-owned environment of CPI Property Group. The company’s operating model remains centred on property assets, rental income, occupancy and portfolio management.

Products and positioning
A listed Austrian real estate investment company focused on diversified, income-producing property assets across Austria, Germany and Central and Eastern Europe.
Commercial real estate
Office properties
Office buildings are S IMMO's largest property category. The company holds and manages office assets intended to generate recurring rental income from business tenants across its Austrian, German and Central and Eastern European markets. Office exposure forms the core of the portfolio by property type and is complemented by retail, residential and hotel assets.
Commercial real estate
Retail properties
S IMMO's retail portfolio includes commercial properties designed for shops and other consumer-oriented tenants. These assets diversify the company's rental-income base beyond offices and provide exposure to retail locations within its European investment markets.
Residential real estate
Residential properties
Residential properties form a smaller component of S IMMO's diversified portfolio. They provide exposure to housing-related rental income and complement the company's larger office and commercial real estate holdings.
Hospitality real estate
Hotels
Hotel properties are part of S IMMO's mixed-use investment portfolio. Hotel ownership adds hospitality exposure to the company's office, retail and residential holdings, with income linked to hotel operations and property occupancy.
Real estate security
s-Immo-Invest participating certificate
The s-Immo-Invest participating certificate is the successor to the earlier s Immobilien-Fonds Nr. 1 real estate security. It represents the investment-instrument heritage from which the modern S IMMO listed share and corporate identity developed.
