What OAB does
OAB AG (OAB Osnabrücker Anlagen- und Beteiligungs-Aktiengesellschaft) is a Hamburg-domiciled, publicly listed holding and investment company that deploys capital into non-listed medium-sized technology and service companies as well as small innovative firms and real estate projects in the German-speaking region (Germany, Austria, Switzerland). Originally founded in 1860 as the Osnabrücker Aktien-Bierbrauerei and continuously quoted on German exchanges since 1870, the entity was dormant for years before being reactivated in September 2020 and strategically repositioned in June 2021 as an impact-oriented Mittelstand investment vehicle. Its shares trade on the Freiverkehr of the Hamburg and Berlin stock exchanges under WKN A3E5D8 / ISIN DE000A3E5D80 (ticker OAB0). The portfolio includes a majority stake in Light Now AG (light-as-a-service), which in March 2025 acquired the business operations of NOVALUMEN GmbH, and the holding has issued Bonus-Wandelanleihe 2026 and Bonus-Anleihe 2028 corporate bonds as part of its funding mix.
The company operates without proprietary technology; it is a financial holding and capital-allocation vehicle rather than a technology business. Its revenue mechanics rest on capital appreciation and distributions from portfolio participations, supplemented by coupon income from issued bonds, with the principal commercial relationship being capital provision to portfolio companies and equity/debt subscriptions by private and institutional investors. Distribution is achieved through dual stock-exchange listings plus direct bond placement, supported by an investor-relations website, press releases, and annual general meetings. The investment thesis is curated around impact investing, digitalization, and sustainability, with deal sourcing and oversight relying heavily on the management network of sole Vorstand (CEO) Alexander Hahn, previously CEO of Deutsche Lichtmiete, and Supervisory Board Chairman Thomas K. Rogalla, a restructuring specialist since 1996.

OAB competitors and assessment
Company assessmentRegional players
- PATRIZIA SE: PATRIZIA is a Germany-headquartered, listed investment manager focused on pan-European real estate. While not a PE peer, it is a relevant comparable for OAB's real-estate sleeve — both being German-listed investment firms combining capital markets funding with operating asset management.
- DIC Asset AG: DIC Asset is a Frankfurt-listed German commercial real estate investment manager. Like OAB's real-estate activities, it combines listed equity with active real-estate investment and asset management, providing an apples-to-apples German listed real-estate peer.
Direct peers
- Heliad Equity Partners GmbH & Co. KGaA: Heliad is a German-listed investment company holding listed and growth-stage private equities, with many investments in German Mittelstand/SME sectors. Its listed PE holding structure and German market focus make it a strong comparable to OAB's public-private equity hybrid model.
- Aurelius SE: Aurelius is a Munich-listed investment firm specializing in European mid-market corporate carve-outs and special situations. Like OAB, it pursues a publicly traded structure to give investors exposure to a diversified, actively managed portfolio of non-listed companies.
- INTICA Capital AG (formerly MPC Capital AG): INTICA (the rebranded MPC Münchmeyer Petersen Capital) is a Hamburg-based, Frankfurt-listed investment and fund advisory company providing PE and real asset exposure to institutional and private investors. Its German-listed structure with PE and real-estate mandates mirrors OAB's hybrid approach.
- mutares AG: mutares is a Frankfurt-listed investment holding focused on acquiring mid-market companies in special situations across Europe. Its listed-vehicle structure, German Mittelstand orientation and active deal-making model align closely with OAB's stated mandate.
- Deutsche Beteiligungs AG: DBAG is Germany's flagship listed mid-market private equity firm. It is the closest direct comparable to OAB in terms of being a publicly listed vehicle providing investors access to German Mittelstand investments through equity listed on a German exchange.
