Who Owns STRABAG SE?

Understanding a company's ownership is key to grasping its strategic direction and market influence. STRABAG SE's journey included an IPO in 2007 on the Vienna Stock Exchange, which altered its ownership structure and governance.

This European construction services group, with roots tracing back to 1835, has evolved significantly. Its vision was to establish an innovative construction enterprise, growing into Austria's largest and a major European player.

Who owns STRABAG SE?

As of late 2024, STRABAG SE holds a market capitalization of around €4.7 billion. The company provides a full spectrum of construction services, from initial planning to ongoing facility management, serving diverse global sectors. Examining its ownership reveals the influence of founding families, major investors, and public shareholders, alongside historical shifts.

The origins of the company trace back to two distinct entities: ILBAU, founded in Austria in 1835, and STRABAG, established in Germany in 1895. These foundational companies underwent significant transformations and mergers over the decades, shaping the current ownership structure.

ILBAU's Austrian Roots

ILBAU began as a family craftsman's business in Austria. It evolved through various legal forms, eventually becoming ILBAU-Aktiengesellschaft in 1972 and its holding company, BAU HOLDING AG, was established in 1987.

STRABAG's German Beginnings

The German counterpart, STRABAG, started with an ironworks venture in 1895 that expanded into road construction. The company name was officially introduced in 1930, and STRABAG AG, Cologne, was listed on the stock exchange in 1949.

Key Mergers and Acquisitions

A pivotal moment in the ownership history occurred in 1998 when BIBAG Bauindustrie-, Beteiligungs- und Verwaltungs-Aktiengesellschaft acquired a majority stake in STRABAG AG, Cologne. This move positioned them as sister companies.

Brand Unification

In 2000, the BAUHOLDING STRABAG Group unified its brand identity, consolidating operations under the core STRABAG brand across Europe. This marked a significant step in integrating the two foundational entities.

Parent Company Establishment

By 2001, BAUHOLDING STRABAG AG became the majority shareholder and parent company of STRABAG AG, Cologne. This consolidation laid the essential groundwork for the modern corporate structure of the group.

Early Ownership Details

While specific initial equity splits from the earliest founding phases are not detailed, these strategic alignments and mergers were crucial in establishing the company's ownership trajectory.

The early ownership of the company was shaped by the distinct histories of ILBAU and STRABAG, with key developments including the establishment of holding companies and strategic acquisitions that led to their eventual unification. Understanding these foundational steps is crucial for grasping the current STRABAG ownership. The company's business model and revenue streams are detailed in a Revenue Streams & Business Model of STRABAG article.

Key Ownership Milestones

The journey from two separate entities to a unified group involved significant corporate restructuring and strategic acquisitions. These events were critical in defining the STRABAG ownership structure.

• ILBAU founded in Austria in 1835.
• STRABAG founded in Germany in 1895.
• BAU HOLDING AG established as ILBAU's holding company in 1987.
• BIBAG acquired majority in STRABAG AG in 1998.

The ownership structure of STRABAG SE has seen notable shifts since its 2007 IPO, with key developments in 2024 and 2025 significantly impacting its shareholder landscape. These changes have implications for the company's strategic direction and governance.

The historical syndicate agreement, active until December 31, 2022, governed the rights and coordination among Austrian core shareholders and MKAO “Rasperia Trading Limited”. In December 2024, STRABAG SE was informed of Rasperia Trading Limited's transfer back to its former parent, MKAO Valtoura Holdings Limited. However, Rasperia's shares remain under sanctions, impacting the control and disposition of this significant stake. The company's market capitalization was approximately €4.7 billion at the close of 2024. The Haselsteiner family's sale of 2 million shares in March 2025 reduced their holding to 29% and increased the free float. Legal complexities persist, including arbitration proceedings related to rights of first refusal stemming from the original syndicate agreement.

Key Ownership Dynamics

Understanding STRABAG ownership involves tracking significant shareholder changes and legal frameworks. The current structure reflects a blend of family, institutional, and formerly sanctioned holdings.

• The Haselsteiner family holds a 29% stake as of May 2025.
• Raiffeisen/UNIQA collectively own 30.4% of the company.
• MKAO 'Rasperia Trading Limited' accounts for 24.1%, with its shares currently frozen due to sanctions.
• The free float represents 14.1% of the total shares.
• A capital increase in March 2024 raised the share capital to €118,221,982.
• Recent share transfers and ongoing legal claims highlight the evolving STRABAG corporate structure.

The governance of STRABAG SE is structured with a Supervisory Board and a Management Board, where the Supervisory Board holds significant oversight. The company's Articles of Association grant specific rights to holders of registered shares 1 and 2, allowing them to delegate a member each to the Supervisory Board.

As of May 2025, the voting rights associated with registered share 2, previously held by Rasperia, have been suspended due to sanctions, and any disposal of these shares requires Supervisory Board approval. The total share capital stands at €118,221,982, with a general one-share-one-vote principle applying to all bearer and registered shares, meaning there are no broad restrictions on voting rights. While specific details on all current board members and their direct representation of major shareholders beyond the registered shares are not publicly detailed, a syndicate agreement that was in place until December 2022 regulated the nomination of Supervisory Board members and voting coordination among core shareholders. The passing of Klemens Peter Haselsteiner in January 2025, who held registered share 1, means probate proceedings are underway, which could lead to future adjustments in representation for that particular Supervisory Board seat.

Understanding STRABAG's Board and Voting Power

STRABAG SE's corporate structure involves key individuals influencing its direction through board representation and voting power. The current situation reflects ongoing changes in ownership and control.

• Supervisory Board and Management Board are key governance bodies.
• Registered shares 1 and 2 grant specific board nomination rights.
• Sanctions have suspended rights tied to registered share 2.
• Disposal of registered shares requires Supervisory Board consent.

Recent developments in STRABAG SE's ownership landscape include significant shifts and ongoing legal clarifications. Key events over the past 3-5 years highlight changes in major shareholdings and strategic realignments impacting the company's control structure.

The ownership structure of STRABAG SE has seen dynamic changes, particularly concerning the significant stake held by Rasperia Trading Limited. This entity's 24.1% holding in STRABAG SE remains frozen due to sanctions, preventing dividend distribution for the 2024 financial year. This situation has prompted legal action from Austrian core shareholders, initiating a court of arbitration in Amsterdam in October 2024 to clarify rights stemming from a 2007 syndicate agreement. These legal proceedings are crucial for understanding the future control and beneficial ownership of this substantial share block.

Shareholder Activity

The Haselsteiner family reduced their stake in March 2025 by selling 2,000,000 shares. This move aimed to broaden the institutional investor base, increasing the free float to approximately 12.6%.

Investor Base Shift

While the free float saw an increase in institutional investors, a January 2025 shareholder ID indicated a slight decrease in both retail and institutional investors within this segment compared to the prior year.

Strategic Acquisitions

STRABAG has actively pursued growth through acquisitions in 2024 and 2025. Notable additions include the ELCO Group in Luxembourg and Georgiou Group Pty Ltd in Australia, alongside agreements to acquire WTE Wassertechnik GmbH.

Financial Performance and Outlook

The company reported strong financial results for 2024, with an output volume of €19.2 billion and a record order backlog of €25.4 billion. For 2025, STRABAG anticipates an output volume of around €21.0 billion and an EBIT margin of at least 4.5%. The proposed dividend for the 2024 financial year is €2.50 per share. Understanding these financial metrics is key to assessing the company's overall health and its Marketing Strategy of STRABAG.
